Abstract:

An analysis is presented of some problems of designing centrifugal and mixed-flow pumps from the point of view of the energy transfer processes. It was previously shown Ovsyannikov, B. V., Aviatsionnaya tekhnika, no. 2, 1963 that in a centrifugal pump the energy is transferred to the fluid by Coriolis inertia forces and circulation forces i.e., forces associated with the circulation of relative velocities around impeller blades. Formulas are derived for calculating these forces, and relationships are obtained for these forces and certain geometric pump parameters. It is noted that this type of approach to pump analysis makes it possible to explain various relationships established by experience and to obtain new knowledge which would be of great value in designing centrifugal and mixed-flow pumps.
