Target group: Automotive Engineering, Applied Mechanics, Product Development

At Research and Development you will be a key contributor to the next generation outstanding luxury cars from Volvo. Together with other engineers around the world, you and your team will create innovative human-centric car technology that makes life less complicated and more enjoyable for people. Are you interested in design and connected car technology? Do you share our passion for people, the environment and our urge to create a superior driving experience? Research and Development is the place for you to prosper.

The group Air Induction System (AIS) is responsible for the development of air filters and charge air systems to Volvo’s petrol and diesel engines. The highly efficient turbo charged engines in the fuel efficient cars of the future require well optimized air systems, which ensures that the engines get clean air in a lossless manner. The power you get from an engine is determined by the amount of air that you can get to flow through it. High airflow rates has to be achieved with as low pressure drop as possible, while managing the high packaging restrictions in the engine bay.

Background

Topology optimization is an automated process to optimize the shape of the flow path from a given design space. Helyx is a software based on the open source CFD solver OpenFOAM. Helyx has built in Topology optimization functions that we want to evaluate. Other software such as Tosca Fluid also exists.

Scope

The purpose of this thesis work is to develop a method for Topology Optimization for the Air Induction System by evaluating the Helyx software. The method is then to be used to optimize an existing Air Induction System component. Once a design has been finalized, it can then be produced using a 3D printer to be tested physically in both an airflow rig and/or in a Turbocharger test cell.

Deliveries of the Thesis Work:

  • Develop and document a CFD method for performing Topology Optimisation by using Helyx.
  • Apply the method on an AIS component.
  • Validate the design by physical testing.

Profile

  • Good knowledge and interest of fluid dynamics.
  • Desire to work with CFD simulations and scripting.
  • Previous knowledge of open source and commercial CFD codes (OpenFOAM, Fluent, StarCCM+).
  • Knowledge of CAD software (CatiaV5) is not required, but is considered an asset.
  • Interest in vehicles and engines is valued.
  • Self-standing, curious and fast learning.

Duration

  • Period: 1 semester, 30 ECTS points
  • Starting date: January 2018
  • Number of students: Suitable for 1-2 student.
  • Work to be done at dept 97482 Air Induction Systems, Volvo Cars Corporation, Torslanda, Sweden
