Thermal Management of Electric Vehicles and Heat Pumps for Automotive Applications
Topic Overview:
The student will work with results of two finished project Themasys and Ecohep. The main focus will be application of projects results on new issues or processing the project data for computation model validation.
Themasys: The aim of the two-year project is to create a complete system for testing the components of the systems for active thermal management of electric vehicles. This is a very current area, which is addressed by a large number of automotive companies, reflecting the high demands of customers. The components of the system that will be created during the project will be the thermal simulator of the battery, the cabin simulator including the HVAC unit and the data acquisition system. An integral part and one of the outputs of the project will be a set of procedures for component testing using the BUT climate chamber, which will also be the result with the main potential for commercial use.
Ecohep: The aim of the two-year project is to develop a new compact reversible heat pump system (air conditioning/heating) for automotive applications using HC based refrigerant. The entire system will first be designed at a thermodynamic level using simulation models and virtual validation to find the optimum amount of refrigerant in the system to minimize its amount. Next, a functional sample from power and economically relevant components will be assembled and the system will be validated by a series of climatic tests in the BUT climate chamber to confirm its operational parameters. The project will also include a proposal for managing the entire system and plan for its integration into vehicles.

Quality of Fuel Atomization of Small Pressure-Swirl Atomizers
Topic Overview:
Atomization is a process of liquid disintegration into small fragments - drops. A flow of atomized liquid is called “spray” and it is generated in a spraying device - atomizer. This conversion is essential for many industrial applications such as combustion, water cooling, spray coating or food processing. Atomization can by carried out by variety of ways and different forces act to atomize the liquid: mechanical, aerodynamic or ultrasonic. A design of the atomizer depends on its application and operating conditions. The most common type are pressure atomizers due to their simple design. The simplest atomizer type is a plain orifice type whereas pressure-swirl type is more frequently used. This work is focused on the evaluation of spray characteristics of pressure-swirl atomizers for a small-sized jet engine and on possibility to improve the spray. The nonintrusive method Phase Doppler Anemometry was used to measure droplets characteristics such as their velocity and size. Any improvement in spraying performance leads to an increase of the combustion chamber efficiency and any fluctuations may harm the atomization as well as the combustion itself.
Task:
Tentative work plan (we may change it after an interview, where I will try to match your skils with our tasks):
1) Familiarisation with our department & colleagues, visit of laboratories at the department (to see what research is done there, what equipment, measurement devices, projects etc.) (1 week)
2) Training on the measurement of spray from fuel nozzles using optical measurement methods, basics, study of the topic, tasks to test the understanding of the topic (1 week)
3) A literature review on a specific topic in Two-Phase gas-liquid flow (1 week)
4) Experiments on the fuel atomization of pressure-swirl or twin-fluid atomizers; participation on optical measurement of spray from small fuel nozzle, the measurement is done with Phase-Doppler anemometry and high-speed camera. Further possibility is explanation of measured data, their transfer and manipulation (2-3 weeks)
5) A script preparation for various data analyses, and/or statistical and physical processing of measured data in MatLab, Excel… (2-3 weeks); alternatively a composition of equations and preparation of a procedure for calculation of droplet balistics
6) Result analysis (effect of different factors on spray and two-phase flow) and final report. (1 week)
Requirements:
Knowledge of fluid dynamics, basics in optics, basics in experimental work, experience with statistical data analysis welcomed, but not necessary.
Outcomes:
Lit. review, exported data files, report, eventually Matlab scripts.

Development of Energy Efficient Twin-Fluid Atomizer for Effective Post Combustion CO2 and NOx Removal
Topic Overview:
Ever increasing energy demands along with limited availability of alternative and renewable technologies requires using of fossil fuels in today’s world. Burning of fossil fuels for energy requirements results in emission of greenhouse flue gasses such as CO2 and NOx. Post combustion-capture of primary greenhouse gases is one of the methods reducing global warming. This task is provided by a twin-fluid atomizer (atomization is a process of liquid disintegration into small fragments – drops, a flow of atomized liquid is called “spray” and it is generated in a spraying device - atomizer). It produces a spray of aqueous ammonia solutions which scrubs CO2 from flue gasses by chemical absorption process. This project is focused on developing of such a twin-fluid atomizer. Achieving fine spray with 50 μm mean diameter and a narrow drop size distribution is required for effective and controlled scrubbing process. Systematic study of suitability of air-assisted atomization methods with low atomizing gas consumption and advanced atomizer design are the primary objectives of the present project. Developing such an atomizer will allow in effective solvent utilization and reduce the operating costs of the flue gas scrubbing process. This atomizer will also find other applications requiring low atomizing gas consumption and high atomization efficiency. Detailed understanding of spray mixing and droplet-gas interactions in spray columns is critical for increasing efficiency and reducing ammonia slip in spray columns. The computational aspect supported by the experimental finding of this project is aimed to address this issue. The experimental data obtained during the project will form a data strong base for computational simulations of the scrubbing process. Computational models supported by sound experimental data will help in understanding the dynamics of liquid gas interaction and lead towards designing efficient spray columns for flue gas scrubbing.
Task:

Analysis of Flow of Inhaled Fibres in a Model of Human Airways
Topic Overview:
Inhaled fibres can potentially cause inflammation of the lung tissue and interstitium which, after long-term exposure, may lead to lung cancer, malignant mesothelioma or pulmonary and pleural fibrosis. For risk reduction and correct setting of occupational hygiene regulations, it is important to be able to precisely calculate the fate of inhaled fibres depending on their physical characteristics and inhalation conditions. As there is a lack of experimental data on the orientation of fibres, a new test rig has been assembled for visualization and recording of flowing fibres in a replica of the human trachea. Fibres prepared from regular glass fibres produced commercially for blown thermal insulation have been processed, dispersed and introduced into the glass tube with dimensions of the trachea. Visualization was performed using a powerful LED light and a high-speed camera.
Task:
Analysis of data recorded by a high-speed camera, evaluation of angles of rotation of fibres during the flow, analysis of the results using dimensionless criteria, statistical data processing, final report.
Requirements:
Knowledge of fluid dynamics, turbulence, experience with statistical data analysis welcomed, but not necessary. Capability of using MATLAB or Origin for data processing.
Outcomes:
Final report.

Influence of Process Parameters on Properties of Mechanically Alloyed Powder Blends
Task:
To establish optimal processing parameters in mechanical alloying (e.g. weight ratio of milling media to powder content, RPM vs. powder content, influence of liquid phase addition) and to determine influence of key process parameters on the qualities of alloyed powder blends. The preparation of binary powder blends could be carried out using planetary mills. Two prevailing methods are production of powder blend mixtures and mechanical alloying using milling medium. Considering the different mechanical properties of materials, there are no optimal conditions of both methods. As such, it is necessary to establish a knowledge database of suitable (optimal) processing parameters for each material. The task of the student will be to determine the influence of input parameters (e.g. revolution of the mill system, size, shape and ratio of milling medium, processing time) on the properties of the produced blends/alloyed powders.
Recommended for:
The project is opened for students with direct specialization in Material Engineering (with very good knowledge in the field), in the final years of their undergraduate studies.

Modelling the Full-Scale Motorcycle/e-Scooter Accident Based on Real Cases from Accident Database
Topic Overview:
The powered two-wheeler (PTW) riders are among the group of the vulnerable road users (VRU). That means that they are the users which are exposed to the highest risk of injury in road transportation. The PTW’s drivers often travel with a speed higher than a bicyclist, but they had only a little better protection against potential injuries. A helmet is the only one required and forced by the law as personal protective equipment (PPE), which is expected to protect a rider’s body against impact. The PPE market provides a wide spectrum of protectors (gloves, garments, boots, joint protectors), but for daily use, none of them are required to be wearied by the rider. Another safety measure in the road transportation system is a road barrier, which for the PTW should meet different testing protocol than the car/truck barrier. Due to the complicated kinematics of rider-PTW-opposite vehicle (OV) system in the crash conditions, the current tools for accident simulation and reconstruction, in the PTW crash cases, expose problems of simulation stability and computational cost (finite element method- based tools), or problems of insufficient models’ bio-fidelity and/or over-simplification (multibody system based tools).
Task:
Analyze provided motorcycle accident data, rekonstruct the crash configuration in the VPS. Run sensitivity analysis to assess the most influential parameters. Validate reconstructed accident using available validation data. Analyze results and write final report.
Requirements:
Capability of using MATLAB for data processing, basic knowledge of MBS and FEM theory, experience in CAD/CAE (Hypermesh welcome), experience in some computational package.

Pelvic Female Model for Birth Related Injury Prevention
Topic Overview:
Female pelvic floor dysfunctions are very often associated with injuries of pelvic floor structures during vaginal delivery. It is reported that only 9.6% and 31.2% of women deliver with an intact perineum at their first and second births respectively. Therefore, it is imperative that the complex anatomy and physiology of the pelvic floor is fully investigated. The main objective of this study is to improve the existing female pelvic FE model. The work is focused also on identification of material parameters of the pelvic floor tissues. Enhanced model serves for modeling the second stage of the vaginal delivery, where the birth is driven by prescribed head trajectory. Methods preventing birth injuries are then simulated and analyzed.
Task:
Analyze measured data. Simulation of methods preventing birth injuries in the VPS. Run sensitivity analysis to assess the most influential parameters. Analyze results and write final report.
Requirements:
Capability of using MATLAB for data processing, basic knowledge of FEM theory, general notions in anatomy of human body, experience in some computational package.

Female pelvic floor dysfunctions are very often associated with injuries of pelvic floor structures during vaginal delivery. It is reported that only 9.6% and 31.2% of women deliver with an intact perineum at their first and second births respectively. Therefore, it is imperative that the complex anatomy and physiology of the pelvic floor is fully investigated. The main objective of this study is to improve the existing female pelvic FE model. The work is focused also on identification of material parameters of the pelvic floor tissues. Enhanced model serves for modeling the second stage of the vaginal delivery, where the birth is driven by prescribed head trajectory. Methods preventing birth injuries are then simulated and analyzed.
Task:
Analyze measured data. Simulation of methods preventing birth injuries in the VPS. Run sensitivity analysis to assess the most influential parameters. Analyze results and write final report.
Requirements:
Capability of using MATLAB for data processing, basic knowledge of FEM theory, general notions in anatomy of human body, experience in some computational package.
Outcomes:

Autonomus Vehicle’s Occupants Safety
Topic Overview:
New interior design for highly automated vehicles (HAV) provides a comfortable journey to its passengers. They have access to extra room and can change their seats’ location and posture for sitting. These new seating configurations are not necessarily face-forward hence they are called non-standard seating configurations. Face-to-Face and Living Room are the most well-known seating configurations. While all vehicles are equipped with active safety systems that meaningfully reduces the vehicle to vehicle crashes the safety HAVs' passengers is a must. Body parts’ injury assessment either experimental test or CAE simulations can be applied. An anthropometric database is available related to human body nVirthuman in different crash scenarios. The Virthuman is a developed hybrid MBS-FEM model to be used in virtual performance solution (VPS), Pam-crash module. It has such a capability to predict injuries on a body in crash scenarios. The structure of the Virthuman helps to run crash simulations and in consequences injury analysis relatively faster than the other available models.
Task:
Data processing of the current simulations’ result regarding analysing occupants’ injury in crash scenarios. Providing some model modifications (i.e. vehicle interior).
Requirements:
Basic knowledge in Finite Element Method (FEM) and/or Multi-Body System (MBS) method Experience in any CAD/CAE (i.e. Pam-Crash, Abaqus, Ls-Dyna, Hypermesh) is an advantage. Capability of using numeric computing software (i.e MATLAB, Python, Maple, Mathematica) is an advantage.

Investigation of Mechanical Properties of Flexible Materials with an Internal Structure
Topic Overview:
In case of commonly produced flexible materials with internal structure (e.g. polyurethane foam) the forming if this structure is given by chemical reactions occurring as a part of technological process. Controlling of geometric and mechanical properties is then given by chemical composition of production components and other technological conditions. The alternative way how to make such a kind of material is a 3D printing technology when every geometric part of the structure can be intentionally designed. It is way more easier to control the total material density as well as detailed geometric properties.
The research at the Department of Applied Mechanics deals with artificial design of a geometry of 3D printed materials and investigation of their mechanical properties. Once the material was designed and printed it is subjected to mechanical testing in the Laboratory of Experimental Mechanics what is a part of our department. We investigate experimentally the force response to displacement excitation (usually compression tests), and dissipated energy. Simultaneously we develop material model of a structure for a simulation by means of Finite Element Method. We use MSC.Marc software for the computer simulation. Then detailed data analysis is performed for comparison of the experiment and simulation.
Task:
The job description will be adapted to real abilities of internship students and will comprise following activities. These activities and detailed work description and tasks will be given by needs of our research at the time of internship.
- Artificial design of 3D structure.
- Assistance in experimental work.
- Data processing and evaluation.
- (Finite Element Method simulation.)
Requirements:
Programming skills (Matlab is preferred, Python may be useful as well).
Some positive relationship to a field of Stress and Strength of Materials and experimental work.
Outcomes:
This will be specified in accordance with a detailed work specification.
