The Method of Calculating the Mechanical Coefficients of Fluid Mixtures : No.3 The Coefficient of Internal Friction and the Viscosity of Two-phase Fluids

The coefficient of internal friction and one of viscosity of disperse two-phase fluids are simultaneously determined by utilizing a self-consistent cell model and expressed as the functions of the volume fraction of particle phase. It is assumed that the fluid inside the cell is Stokesian and the outside fluid is Stokes-Darcian. Careful examination on the macroscopic notions is necessary to derive the conditions to determine those coefficients. the predictions obtained are satisfactory.
