Master Thesis – Modeling the heat transfer in and around electronic components in a truck using CFD
Introduction
Modeling and simulation of vehicle systems is an important and integrated part of the development process for vehicles. The number of electronic control units (ECUs) in a truck keeps on increasing as well as its heat generation. Some can be cooled by passive cooling, but some generates so much heat that they require active cooling. Modeling this in an early stage is of great importance to be able to decide the most efficient cooling concept.
Who we are
The Thermal Management department within Vehicle Technology is responsible for developing, delivering, and maintaining an optimized Cab Climate and Thermal Supply systems for all types of propulsion installations to all truck brands within the Volvo Group. We are responsible for leading the work with strategies and advanced engineering globally. We are located at Gothenburg and Bangalore and we have close cooperation with the engineering sites located in Greensboro and Lyon. We understand the final customer needs and apply our knowledge to develop technical concepts and solutions that satisfy customer and business needs. The work is based on innovation, shared technology, common architecture and brand uniqueness. We want to make a difference by being there for our customers and by providing uptime and reliable products.
As a master thesis student in the Thermal Management Verification and Validation team you will be a valued contributor to our deliveries and continuous learning. You will be surrounded by a global and diverse team of highly skilled and engaged colleagues who will be interested in the progress of your work and eager to help and support along the way.
Description of tasks and expected outcome
- Literature search about modeling the heat transfer in ECUs
- Explore the Electronics Cooling Toolset in Starccm+
- Building a generic ECU and model the heat sources in different ways (individual components vs a lumped heat source)
- Placing the ECU in a generic truck environment and simulate different cooling concepts
- Documentation of best-practice methodology for ECU cooling simulations
