We are looking for a

PhD – Plasma Torch Simulation Engineer (m/f/d)

Paul Wurth as a global leader in ironmaking technology is actively working on CO2 reduction approaches for the blast furnace-based iron production route. Therefore, a dedicated R&D group focusing on different CO2 reduction techniques along with the usage of green energy and hydrogen has been set up. One of the most promising research paths for the modernization of the blast furnace steel production route is the EASyMelt concept developed by Paul Wurth and integrating plasma torches.

As a Plasma Torch Simulation Engineer, your primary responsibility will be to design and simulate plasma torches for industrial applications. You will work closely with a team of engineers and researchers to develop innovative solutions for plasma torch technology.

Your main tasks (during internship):

Running the developed OpenFOAM Solver for different scenarios
Estimating of thermodynamic and transport properties of the plasma using statistical mechanics.

Your main tasks (during PhD):

Develop a numerical model for plasma torches using simulation software such as OpenFOAM or Code_saturne
Collaborate with the experimental team to validate the simulation results and improve the accuracy of the models.

What do we expect?

PhD or Master's degree in Mechanical Engineering, Chemical Engineering, Physics, or a related field
Strong understanding of numerical methods
Strong understanding of plasma physics
Experience in numerical simulations using software such as OpenFOAM
Familiarity with programming languages such as C++ or Python
Strong analytical and problem-solving skills
Ability to work in a team environment
Proficiency in English. French or German language skills are considered an advantage.

What do we offer?

Internship supported by a PhD in an international team in one of Luxembourg’s leading industrial players
Interesting development possibilities in an international, innovative and dynamic company
Flexible working hours and entitlement to leave, which exceeds the legal frame
Exciting and diverse topics and work streams.
