Research project

This project is to study the influence of electromagnetic fields on flow, turbulence and heat transfer in conducting liquid. We will:

• Develop computational models for anisotropic turbulence in MHD flows of conducting liquids.
• Validate the models in an experimental setup mimicking continuous steel casting.
• Apply the models to improve electromagnetic flow control for continuous steel casting.

• How do large scale magnetic fields influence turbulence and heat transfer in moving conducting liquids?
• How do large scale magnetic fields influence the flow at, and the heat transfer towards, free surfaces in conducting liquids?

You will be working with another PhD student with experience in experimental laboratory research with lasers and optical techniques (e.g., LDA or PIV). You will also work in close interaction with a major European steel manufacturing company and a major European manufacturer of large, industrial (electro)magnets.

Requirements

We are looking for a candidate with

• an MSc degree in (applied) physics, or mechanical, aeronautical, civil or chemical engineering
• a solid background in fluid dynamics and turbulence,
• an excellent knowledge of written and spoken English, and
• a top 20% ranking during his/her BSc and MSc.

He/she should have a strong interest and some experience in Computational Fluid Dynamics, as well as good skills in the use of computer systems and computer programming.

Department

The focus of the Department of Multi-Scale Physics (http://www.msp.tudelft.nl/) is developing the conceptual understanding and enabling detailed control of fluid dynamics and transport phenomena at all relevant time and length scales as occurring in a wide variety of industrial and environmental processes. Our approach is typically ‘Applied Physics' and strongly technological. We aim at combining scientific rigour and industrial relevance in an internationally recognized centre of excellence where the participating individuals have the opportunity to contribute to the science behind the technology.

Employment conditions

The successful candidate will be employed full-time by TU Delft for a fixed period of four years within which he or she is expected to write a dissertation leading to a doctoral degree (PhD thesis). The starting salary for a PhD is €2042 gross per month increasing to a maximum of €2612 gross per month in the fourth year.
TU Delft offers an attractive benefits package, including a flexible work week, free high-speed Internet access from home, and the option of assembling a customized compensation and benefits package. Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities. Delft University of Technology strives to increase the number of women in higher academic positions; women are therefore especially encouraged to apply.
