• The coefficient of internal resistance in dispersive two-phase flow is considered. The method of self-consistent cell model is applied to determine the coefficient as a function of the volume fraction of particle phase. A certain spherical cell is formed around a randomly chosen particle. It is assumed that inside the cell the fluid is Stokesian while outside the fluid is Stokes-Darcian. The solutions in both sides are connected on the cell surface by suitable conditions. The condition of coincidence is considered, which is indispensable to determine the coefficient considered and supplements the boundary conditions. The numerical calculation is carried out and the prediction is reasonable.
