Abstract

The effect of oscillatory flow properties, the Reynolds number and the KC number, on turbulence generated by a porous media was investigated by hydraulic experiment. Violent turbulence was generated when interstitial velocity exceeded a critical level. Turbulent energy generated in pores increased as the Reynolds number increased. In a porous media, difference between minimum and maximum values of turbulent energy was increased as the KC number increased. And outside porous media, turbulent energy spread widely as the KC number increased. Under unsteady oscillatory flow, maximum turbulent energy was larger than that of unidirectional steady flow.
