This thesis work will be carried out within the Exhaust System Group as well as within the Engine CAE-Fluids Group, both which are parts of VCC's Vehicle Propulsion organization. The Exhaust System group develops and optimizes the exhaust system with respect to engine performance, NVH (Noise, Vibration, and Harshness), durability, etc. The Engine CAE-Fluids group performs and develops CFD methods for all engine related functions.
Background
Exhaust backpressure is an important parameter to consider in development of exhaust systems. All parts of the exhaust system contribute to backpressure, such as straight pipes, bent pipes, and mufflers. Backpressure can be measured e.g. in a flow rig or an engine dyno bench. However, building physical prototypes for testing are often very costly and the lead times from order to delivery date are long. Simulations are therefore an efficient alternative to physical testing given that they provide results with reasonable accuracy. 3D CFD can predict fluid fields at high accuracy, but it demands significant amount of computational power. 1D CFD is a less accurate alterative but it requires less computational resources.
The goal with the master's thesis is to evaluate 1D and 3D CFD methods and investigate the accuracy in different parts of the exhaust system.
Scope
The master's thesis includes a literature study of previous work. Simulation of the exhaust system will then be performed with 1D and 3D CFD as well as validation of the results with physical flow bench measurements.
The student will work in the Exhaust System group together with the Engine CAE-Fluids group.
Profile
* We are looking for a highly motivated student that have a genuine interest in cars, calculations and product development.
* Preferably the student has a background with courses in Computational Fluid Dynamics (CFD) and multiphase flow.
* The student should ideally be familiar with 1D or 3D CFD software such as GT-SUITE, STAR-CCM+, ANSYS Fluent, OpenFOAM.
* Communication skills are important since information will be needed from several different parts of the company.
Duration
* Period: one semester, 30 ECTS points and will be performed at Volvo Cars
* Starting date: January 2018
* Number of students: suitable for one student.
Application
* Attach your resume and cover letter stating your interests within the given area and your thoughts and credentials.
* Please note that applications arriving later then the last application date will not be taken in consideration.
* Selection will be ongoing during the application period.
