Flow Simulations over Porous Media-Comparisons with Experiments
A closure model is presented to compute turbulent flow over and through porous media.The model is based on the Darcy and Forchheimer term which are also applied to a Reynolds-stress turbulence model.The implementation of the model into a flow solver is validated with windtunnel experiments of a 2D-wing with a porous trailing edge.Pressure and PIV measurements are performed for the determination of integral force coefficients and the understanding of the detailed flow field.The measurement data are discussed and compared with the results of the numerical computations.The simulations match the experiments very well and reproduce the flow phenomena correctly.This yields confidence for using the closure model for more general applications.
