Master Thesis Student - CFD Thermal

Req ID:469522 

At Alstom, we understand transport networks and what moves people. From high-speed trains, metros, monorails, and trams, to turnkey systems, services, infrastructure, signalling and digital mobility, we offer our diverse customers the broadest portfolio in the industry. Every day, more than 80 000 colleagues lead the way to greener and smarter mobility worldwide, connecting cities as we reduce carbon and replace cars.

We are looking for a Master thesis student to join our team in Västerås!

Topic proposed: ​CFD based methods to generate thermal digital twins railway traction converters

Duration: 20 weeks, on-site

Background 
​Alstom’s latest traction platform is designed to deliver very high performance density. This is accomplished by the effective utilization of the latest generation of power semiconductor devices in a new standardized and scalable packaging for railway traction. Simulations are used to effectively utilize this performance potential, where accurate thermal models are critical. However the models need to combine high fidelity with light computational loads and short processing time.​  

 
Problem description and goals 
The thesis project will focus on developing and validating procedures to derive Reduced Order Models from CFD simulations for a given product design from which machine learning based digital twins can be generated for use in performance simulations. The following steps are foreseen: 

1. Introduction to electric railway traction design 

2. Introduction to Alstom’s modular traction platform thermal design and mission profiles 

3. Introduction to Alstom CFD tools 

4. Survey of state of the art research and tools in CFD modeling methods for digital twins 

5. Model development for Alstom product 

6. Evaluation of model accuracy 

7. Development and evaluation of an optimum workflow  

8. Analysis, conclusions and reporting 

The scope of the project can be adapted to suit one or two thesis students.
