Master Thesis Project
Title: 1d-3d CFD Development, validation and optimization of climate and energy-related models for electromobility
Subject: Thermal Management and Energy Optimization, CFD
With the increased demand for electrification of the transport system, new challenges arise that need to be faced and overcome. One of the major challenges for electric vehicles is to have the range and climate comfort comparable to a vehicle with a combustion engine. More precisely put, developing an electric vehicle which has for the passenger a satisfying range in various weather conditions, without sacrificing passenger comfort.
This thesis will build upon already existing methods and models but further develop them by using both System Simulation solvers and 3d-CFD solvers.
The overall aim of the thesis work is to:
- Investigating areas in the system that could be further optimized with regards to energy usage, while also taking into consideration parameters such as thermal comfort.
- Validation and comparison of existing cabin comfort models and further develop existing models to enhance their usability
- Developing a cabin model that is highly accurate, yet feasible to integrate in a larger system model. This would involve a detailed 3D-CFD simulation which is compared to coarser models to find a model that balances runtime and accuracy. Mesh quality and turbulence model could be important parameters to evaluate against thermal and fluid quantities. If feasible this could also include thermal comfort modeling and estimations.
- Investigating how the passenger comfort and battery cell health are linked on a more detailed level
- Finding places where energy usage could be further optimized by exploring a more complete CAE roadmap
- Enabling more interlinked simulations on complete vehicle
- Finding the best balance between cell quality and build in the mesh and model accuracy with respect to temperature and flow fields
- Finding the best balance between cell quality and build in the mesh and model accuracy with respect to cabin comfort with a thermal manikin
- Finding how the comfort of the passenger could affect the health of the battery cell
- Master student in technical physics, mechanical physics etc.
- Good knowledge in fluid dynamics, thermal dynamics and numerical simulations
- Understanding and interest in electric vehicle systems are also preferred
