Thesis work: Measurement of Engine Bay Air Flow

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?


Measurement of Engine Bay Air Flow using Laser Doppler Anemometry



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 still need to be validated against experimental results.

The purpose of this thesis work is to investigate the actual flow field behind different components of the engine bay in the controlled environment of a simplified engine bay rig at Volvo Cars. The measurements will be performed with Laser Doppler Anemometry (LDA), a non-intrusive flow measurement method that allows precise measurements in multiple directions.

The aim is to provide a better understanding of flow phenomena that can be encountered in the engine bay, which will later help to develop numerical tools that give accurate results in an appropriate lead time.


Detailed description of thesis work:

The first step would be literature research about appropriate theoretical approaches that the thesis will be based on. Second, the student will familiarize himself/herself with the measurement equipment. Finally, the student will perform measurements on different configurations, evaluate and analyse the data, as well as document and present the findings.



  •  Have an education in physics, mechanical/automotive engineering
  •  Strong knowledge of fluid mechanics
  •  Ability to work independently
  •  Experience with experimental techniques is a plus
  •  Fluent in English (Spoken & Written).


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

 Starting date: February 2020.

 Number of students: Suitable for 1-2 student
