Current involvements

waLBerla

  • I am involved in the development and validation of the multi-physics software waLBerla. Its aim is to provide a flexible framework for CFD simulations and beyond that efficiently makes use of current and future supercomputers.
  • My special focus there is on particulate flows, i.e. the description of particle-fluid interactions. Applications are the sediment transport in river beds or fluidized bed reactors.

Teaching

  • I lead the exercises for the courses “Simulation and Scientific Computing 1” and “Simulation and Scientific Computing 2”, which are one of the key lectures in the Computational Engineering program.
  • Formerly, I was the tutor for the course “Numerical Simulation of Fluids”. Therein, the students got to know the concepts of CFD and apply a suitable discretization method to finally come up with a self-implemented fluid flow simulator.
