Thesis work: Development of a CFD method

Let's create the future together.

At Volvo Cars, we believe that being curious and truly committed to understanding people is the key to future success. We are people who care about other people, working together to create new technologies and innovations for safe, sustainable and convenient mobility. Want to join us?

 

Development of a CFD method for predicting the thermal effects in a HEV during transient conditions

 

Scope:

The long term aim in the vehicle development is to shift from physical testing towards virtual simulations for verification purposes. This will facilitate cost reductions, decreased energy consumption during the development process, and increased capability to foresee and enhance life time of critical components. Over the last decades the use of computational fluid dynamics (CFD) in the development of cars has grown increasingly, but the simulations are usually limited to steady-state conditions.

The purpose of this thesis work is to develop a CFD method to predict the thermal effects on the battery pack in a hybrid electric vehicle (HEV) during transient conditions. This method would be implemented to predict temperature loads during highly dynamic driving situations, e.g. city traffic, aiming to ensure optimal thermal conditions for the battery pack.

 

Detailed description of thesis work:

The thesis work would include a literature research about state of the art CFD methodologies, followed by hands-on work in creating, meshing and setting up a (simplified) virtual model representing a real vehicle. Finally, the student(s) will develop and propose a methodology that is feasible within the industrial constraints, i.e. limited by computer resources and product development time frames. The conjugate heat transfer phenomena will be analysed using commercial CFD codes.

 

Do you fit the profile?

Have an education in physics, mechanical/automotive engineering

 Strong knowledge of heat-transfer and applications to vehicle engineering

 Strong knowledge of fluid mechanics and CFD

 Experience with Taitherm and StarCCM+ software packages is a plus.

 Fluent in English (Spoken & Written).

 

Duration:

 Period: 1 semester (20 weeks), 30 ECTS points.

 Starting date: February 2020.

 Number of students: Suitable for 1-2 student
