Transport is at the core of modern society.

Imagine using your expertise to shape sustainable transport solutions for the future? If you seek to make a difference on a global scale, working with next-gen technologies and the sharpest collaborative teams, then we could be a perfect match.

What you will do At Vehicle Engineering CAST Platform Platform Energy you will contribute to the transformation of our company, the transport industry and society at large.

We use Computational fluid dynamics (CFD) in our platform development, which is an indispensable tool for evaluating aerodynamic features in modern vehicle development.

The pursuit of sustainable transport solutions and lower emission limits set by authorities are putting more focus on CFD simulations and aerodynamic improvements to reduce emissions.

An optimal aerodynamic shape is perhaps even more important for electric vehicles, where it has a major impact on range.

There are multiple strategies for shape optimization of a vehicle, but they usually require lots of CFD simulations, which limits the industrial applications due to the high simulation cost for commercial vehicles.

Reduced-order modelling aims to solve this problem. It reduces the dimensionality of the optimization problem and can lower the number of simulations needed.
Aim The aim of the master's thesis is to evaluate reduced order modelling (ROM) of aerodynamic simulation methods. The thesis should determine the feasibility and performance of an industrial ROM application for commercial vehicles.

Specifically, the aim is to evaluate:
The possibility to perform shape optimization of a component (e.g. bumper spoiler), using a reduced CFD simulation of a subdomain, with boundary conditions from a full-vehicle ROM model The performance of ROM model as a simulation database; to evaluate cross-correlations of components and identify their influence on the vehicle performance Method You will start with a literature study, define parameter space and create DOE matrix then run CFD simulations of the DOE matrix.

When ready, you will create and evaluate ROM model, shape optimizing of component using ROM model and shape optimizing of component using CFD simulations on subdomain with boundary conditions from ROM model.

Lastly evaluate performance of ROM model as a simulation database, for instance to evaluate cross-correlations of components

Your future team Platform Analysis Energy within Common Architecture and Shared Technologies, acts as a catalyst for innovationwithin Volvo GTT by streamlining method development andleveraging collective expertise.

Aiming to drive early phase development towards energy efficiency andprocess improvements through simulation advancements, contributing to the creation ofsuperior, sustainable, and cost-efficient products.

In the team we have experts in aerodynamics, energy optimization, simulation method developers and other expertise. We work as a global team with the different Volvo sites around the world.
Who are you? Do you dream big? We do too, and we are excited to grow together. You are a M.Sc. student with a strong mathematical background in the areas of physics, mechanical or automotive engineering. Preferably with experience in Star-CCM+ and/or ModeFrontier. You are curious and have strong ability to learn new technologies. You have positive energy and excellent written and verbal communication skills.

What's in it for you? We can offer you the opportunity to work together with highly skilled colleagues in an exciting, global environment which provides opportunities to develop both professionally and personally.

Our daily work is performed in an international environment giving the opportunity to interact with highly committed colleagues from different cultures.

We trust the individual and act as a team, stay close to the product and provide opportunities for professional and personal growth.

Ready for the next move? The thesis will be carried out at Volvo's office in Gothenburg, Sweden, with an optional stay at Optimad's office in Turin, Italy.

It will be a full year master's thesis performed during the fall of 2024 and spring of 2025 by one student and covers 60 ECTS.
