Convective mass transfer in collector-drainage system

Mathematical model of convective mass transfer in collector-drainage system is described. Collec tor-drainage system consists of two adjacent channels with permeable partition. Numerical solutions for pulsating backward flow are presented. Velocity of filtrations $V(X)$ and time dependence of component concentrations for different entrance Reynolds numbers $\mathrm{Re}_0$, relative length of channels $L/d_{\text{э}}$ and resistance of permeable partition $R_{\text{эф}}$ are found.
