| Abstract | A finite volume method based Cartesian grids is adopted to solve the Reynolds averaged Navier-Stokes equations using a k-ε turbulence model and porous media model for the study of the porous effect on the flow evolution as a large depression internal solitary wave propagates over a porous trapezoidal obstacle. Numerical results reveal that as the porosity increases, the waveform inversion becomes unapparent and is not found in the porosity higher than 0.2. In addition, the magnitudes of vorticity and turbulent energy seriously decrease because of acute reduction of the production term, which is induced by percolation and wave-pore interaction. |
