A multiphase non-Newtonian hydrodynamic model has been developed to predict the spatial and temporal distributions of pressure, relative motion between solids and liquid, solids concentration, and slurry shear rate and viscosity. This model includes separate continuity and momentum equations for each phase and extends the well accepted power-law, non-Newtonian constitutive relationship for shear stress calculations. The model has been partially validated by comparison with single-phase power-law non-Newtonian flow theory and the literature data. The present model has also been used to analyze the pure water, No. 2 diesel fuel and coal/water slurry data measured by using high pressure and high shear rate capillary tube systems. Excellent agreement has been obtained between the calculated and measured values on mixture shear rates and viscosity, mass flow rates, and pressure. 19 refs., 5 figs., 4 tabs.
