Background
The rapid evolution of the automotive sector toward electric vehicles is significantly propelled by the technological advancements in thermal management systems. Battery Electric Vehicles (BEVs) exhibit heightened sensitivity to temperature control. The optimal operating temperature window for BEV batteries is notably narrower, and the traction battery is responsible for supplying energy to critical functions, such as climate control, directly influencing the BEV's driving range. Therefore, having an optimized thermal management system is key to ensure the efficient operation of BEVs without compromising performance or climate comfort.
This master's thesis project centers on the prediction and simulation of Battery Electric Vehicle (BEV) heat pump system performance in cold climates, with a particular focus on addressing the critical issue of frosting. Frost formation on heat exchangers can significantly impact the efficiency, lifetime, and overall performance of these systems. It can hinder heat transfer, reducing the system's ability to efficiently warm the vehicle's interior or maintain the battery's optimal operating temperature. Hence, there's a critical need for reliable methods to simulate frost formation under varying conditions, enabling a deeper understanding of the intricate relationship between environmental factors and heat exchanger performance.
Additionally, this research emphasizes the equally vital aspect of defrosting. Effective defrosting strategies are indispensable for preserving vehicle comfort and performance. Developing mathematical models that accurately predict the onset of frost, the accumulation of frost, its impact on heat transfer rates, and the defrosting process is pivotal in advancing BEV heat pump systems. By bridging the gap between theory and practical application, this thesis seeks to contribute to the development of more reliable and efficient BEV heat pump systems. The research follows a comprehensive approach, commencing with a comprehensive review of the current state of research in the field. Subsequently, it focuses on numerical modeling of the frost and defrost phenomena, aiming to enhance existing methodologies. Lastly, these models will undergo rigorous verification against experimental benchmark data to ensure their accuracy. Ultimately, the research aims to enhance the efficiency and reliability of BEV heat pump systems, particularly in cold climates, thereby contributing to the ongoing evolution of electric vehicle technology.
We are seeking two Master students with a background in Mechanical Engineering or a related field for this research project. Candidates with prior experience in working with 1D or 3D Computational Fluid Dynamics (CFD) tools, particularly GT-Suite and Star-CCM+, will be highly regarded.
Applicants should demonstrate a strong foundation in thermodynamics, heat transfer, and fluid dynamics, as these are fundamental to the research focus. Additionally, proficiency in programming and data analysis skills will be beneficial.
If you have a preferred co-worker in mind to collaborate with on this thesis, please include their name in your cover letter when applying. Collaborative efforts and a diverse skill set will enhance the overall research outcome and provide a well-rounded perspective on the project's objectives.
