Turbulent drag reduction by spanwise oscillations of a channel wall with porous layer

•Turbulent open channel flows with an oscillating wall covered with porous medium layer are investigated by DNS based on LBM.•An analytical solution to Stokes second problem with two different kinds of fluid is derived.•Dependencies of porous medium parameters on drag reduction are shown and a combi...
