On the Flow in the Impeller of Centrifugal Compressor with Inducer

抄録

An analysis of a flow through the impeller of a centrifugal compressor which consists of inducer and radial vanes, is presented. The three-dimensional flow through the actual impeller is replaced by a two-dimensional inviscid subsonic flow model. The numerical calculation is carried out by the use of the singularity method. Influences of parameters, that is, Mach number of the rotational speed, impeller width ratio, dimension of the inducer etc. upon the impeller performance and upon the velocity distribution along the blade are investigated.
