要約

Predictions of steady and unsteady injection driven flows in a plane channel are performed by solving the averaged Navier-Stokes equations using a compressible Reynolds stress model. The boundary condition for the fluid injection through the porous wall has been formulated by taking into account experimental investigations. For the steady flow, laminar to turbulent regimes are reproduced in good agreement with the experimental data. For the unsteady flow, the resonant frequency as well as the coherent flow structures are fairly well predicted with the experiment.
