The Professorship "Data-Driven Simulation of Fluids on High-Performance Computers" is uniquely positioned at the intersection of fluid dynamics, data science, and high-performance computing. Our group develops innovative data science methods (data assimilation, machine learning, and uncertainty quantification) to advance understanding and improve predictions of multi-scale physical systems such as:

  • aerodynamic turbulent flows
  • laminar-turbulent transition
  • subsurface flows in porous media
  • particle laden flows
