Large-Eddy-Simulation of turbulent magnetohydrodynamic flows

A magnetohydrodynamic turbulent channel flow under the influence of a wallnormal magnetic field is investigated using the Large-Eddy-Simulation technique and k-equation subgrid-scale-model. Therefore, the new solver MHDpisoFoam is implemented in the OpenFOAMCFD-Code. The temporal decay of an initial turbulent field for different magnetic parameters is investigated. The rms values of the averaged velocity fluctuations show a similar, trend for each coordinate direction. 80% of the fluctuations are damped out in the range between 0 Keywords: magnetohydrodynamic, Hartmann flow, periodic channel flow, Large-Eddy-Simulation, k-equation subgrid-scale model, Open-FOAM, MHDpisoFoam
