INTERRELARIONSHIP BETWEEN THE EFFICIENCY CHARACTERISTICS AND THE CENTRIFUGAL FORCES AT DESIGN AND OFF DESIGN FLOW RATES AMONG AXIAL FLOW FANS, AND COMPRESSORS

摘要

In the present paper, the fluid flow conditions through axial flow fans, and compressors, are replaced and discussed as the fluid flow conditions through conduit pipeline with a rotating impeller in it. It became clear that the centrifugal forces acting throughout impelling blades are strongly interrelated with efficiency characteristics at design and off design flow rates among axial flow fans, and compressors. In the favorable axial flow fans, or the compressors, centrifugal forces may act to fluid particles stronger than those in the less favorable fans, or the compressors. They may act stronger as much the efficiency characteristic is much favorable, both at design and off design flow rates.
