ABSTRACT

A procedure of the axisymmetrical diffuser construction is developed for incompressible liquid flows at high Reynolds numbers with prescribed characteristics of pressure distribution on their surfaces and small frictional losses inside the diffuser. The numerical solution of the problem taking into account the influence of the boundary-layer thickness on the external nonviscous flow is obtained, and the influence of variation of design conditions for the flow parameters in the inlet cross section on the characteristics of the flow in the diffuser is considered.
