Learning Outcomes
Competences
Students know the most important mathematical models used in fluid power. They are able to abstract models from circuit schematics and data sheets of fluid power systems and componentes. They gain an insight into the topic of computationally efficient implementation of wave propagation problems.
Skills Knowledge
  • Derivation of higher order difference quotients for all differential operators found in the Navier-Stokes equations (k3)
  • Semi-discretization of partial differential equation systems - Method of Lines (k3)
  • Tuning of time integration algorithms to the spectral structure of the semi-discretization (k6)
  • Optimization of computation time by domain decomposition and parallel computation (k6)
  • 3D compuational fluid dynamics with OpenFOAM (k3)
Recapitulation of basics from fluid mechanics with a focus on weakly compressible liquids in high pressure applications.

Condensation of simpler models from the general three-dimensional formulation:

  • Lubrication gap theory with Reynolds equation and elasto hydro-dynamics of journal bearings as examples for a spatially two-dimensional theory.
  • Wave propagation in transmission lines as a spatially one-dimensional problem with

expansion to frequency dependent friction (1.5D theory, Zielke-Suzuki method).
