2130910 – CFD in der Energietechnik

The course is aimed of giving the fundamental of Computational Fluid Dynamics (CFD) for energy technologies. Computational techniques for solving Navier-Stokes and Energy equations with emphasis on turbulent heat and mass transfer are introduced. Finite volume method and solution of systems of linear algebraic equations are discussed. Error control, accuracy and stability are discussed and demonstrated. Reynolds-Averaged-Navier-Stokes (RANS) equations and computation of turbulent flows are discussed and demonstrated. Explicit vs. implicit time stepping methods. The course consists of both, a theoretical and a practical component. The former will deal with the derivations and properties of the methods and models for CFD. The practical part will make use of open source CFD computer program OpenFOAM to give a "hands on" insight into the simulation of turbulent flows.
