Karlsruhe: Working Student: Numerical Investigations in Solid Propellant Combustion

As one of the oldest and largest Fraunhofer institutes, the Fraunhofer Institute for Chemical Technology ICT has special expertise: by linking the diverse research fields of polymer engineering, chemical processes, explosives technology, safety and security, and energy and drive systems, it achieves decisive breakthroughs. Examples can be found in lightweight construction for mobility, in environmentally friendly chemistry, in applications for the aerospace and military sectors as well as in life-cycle assessments, recycling and sustainability concepts – which you could soon help to create!

How does a solid propellant burn under extreme conditions?
In our research group “Interior Ballistics & Detonics” at Fraunhofer ICT, we investigate exactly this question. We combine experiments with computational simulations to understand the combustion of solid propellants across different scales.

You will further develop an existing simulation code based on the discontinuous Galerkin method. In doing so, you will implement various numerical methods and analyze how they influence the stability, accuracy, and efficiency of the calculations. Different model assumptions for propellant combustion will be varied, and the results will be compared with existing experimental data.

You will learn how complex thermal process are modeled and simulated, develop an understanding of computational methods in practice, and contribute to realistically representing physical processes in energetic systems.
