INVESTIGATION OF CHANNEL VANED DIFFUSER OF CENTRIFUGAL COMPRESSOR UNDER VARIABLE CONDITIONS,

Abstract

In centrifugal high-pressure compressors, considerable losses occur in the vaned or ducted diffusor for transforming kinetic into potential energy which is located directly behind the impeller. These losses considerably lower diffusor efficiency. Analysis of the effect of the diffusor geometry on its efficiency was made. It was concluded that minimum losses in the ducts of a vaned diffusor occur at minimum flow rates, while minimum losses in the flow through the impeller occur at maximum flow rates. The diffusor should therefore be designed to minimize the overall losses in both elements. (Author)
