Abstract

The flow of a viscous incompressible liquid in the lateral cavity of rotation of centrifugal pumps and gas turbines of liquid rocket engines is considered. Based on the theory of the spatial boundary layer, a system of equations has been developed to determine the coefficient of moment of resistance, which makes it possible to determine the mechanical (disk) losses and efficiency of the unit. The coefficient of the moment of resistance depends on the circumferential frictional stresses, which depend on the thickness of the spatial boundary layer, which for a limited cavity cannot develop indefinitely as with the longitudinal flow around the plate. The effect of the fusion of boundary layers on the wall and on the disk on the mechanical losses of the rotor is considered. Numerical data on the processing of various designs of aggregates are presented.
