The lab course gives an application oriented introduction to the following topics in computational fluid dynamics (lecturers may select certain deepening aspects):

  • Modelling of fluid flow via the Navier-Stokes equations
  • Finite-Difference methods for spatial discretisation of the partial differential equations
  • Semi-implicit time-stepping methods for incompressible flow
  • Iterative solvers for the pressure Poisson equation
  • Domain decomposition and parallelisation
  • Treatment of boundary conditions and obstacles in the flow
  • Free surface flows
  • Integration of transport equations
  • Visualisation techniques for fluid dynamics: particle tracing, streamlines and streaklines

The programming language will be C.

The lectures accompanying this lab course will be conducted in English. The assignments will also be given in English. Completed assignments will be presented by the students in English or German.
