Computational Fluid Dynamics at HLRS University of Stuttgart

Computational Fluid Dynamics at HLRS University of Stuttgart

The numerical fluid dynamics is one of the most computer-bound disciplines. Using the fundamental set of partial differential equations (the Navier-Stokes-Equations often supplemented by turbulence models, the energy equation etc) general problems of fluid flow are solved.

The solvable problem size is until these days still small with respect to the requests. Nevertheless the program development is pushed in an intense manner. The programs are expanded in the direction of chemical reaction, combustion, interface problems between fluid and solid, and more. The advantages of the numerical simulation compared with the experiment are evident. For example, difficult or impossible measurements can be replaced by computation. Problem dependend fluid flow effects can be realized without disturbing the flow like in experiments happen.

For the solution of numerical simulation problems in fluid dynamics together with their various border regions, the computer center offers different commercial and open source simulation programs.

The institutes of the university develop adapted simulation programs for special purposes, as long as no commercial program is able to solve the problem. Some of these developments are based on commercial programs.

While applying the simulation programs the computer center offers intensive user support. This support includes:

  • analysis of the physical problem
  • development of the mathematical model
  • description of the material properties
  • development of the mesh
  • adaption of the program
  • handling of the program
  • postprocessing
  • interpretation of the results

Moreover projects and tight cooperations with industry and institutes of the university are carried out in numerical simulation.
