Abstract:
Due to the potential advantages and applications of porous materials in aerodynamic and aeroacoustic applications, a porous-fluid coupling solver under compressible turbulence circumstances is of significance for CFD researchers. In this paper, a porous-fluid coupling method for compressible turbulence problems based on a k−ω model is proposed and implemented in the finite-volume-based in-house code Aeroacoustic and Aerodynamic Investigation Simulator (AAISIM). At the porous-fluid interface, the conservation equations of mass, energy, turbulent kinetic energy, specific dissipation rate and isentropic condition are solved to balance the flux through the interface. The stress jump condition and turbulence wall function are also employed for the treatment of the permeable wall. For the Beavers and Joseph’s problem, the current results show good agreement with previous Direct Numerical Simulation results for a Reynolds number of 5500. Flat plates with a porous section in the middle and at the trailing edge are simulated and compared against experimental data thus providing a validation of this porous-fluid coupling method.
