The fluid flow in a filter chamber, consisting of a rotating disk and a stationary plate, has been numerically investigated. A proposed model provided acceptable predictions for shear rate and frictional torque in laminar and turbulent flow regimes. Owing to the pronounced effect of the shear stress on the filtration rate, the data obtained were used in analysis of the influence of hydrodynamics on the shear stress field in the filter chamber.
