Studies on Circular Cascades for Return Channels of Centrifugal Turbomachinery : 2nd Report, Flow and Performance of Cascade

概要

論文の詳細を見る
Flows and performances of the cascade designed in the 1st Report were examined experimentally. The main results are as follows. (1) The flow pattern through the cascade is very complicated owing to the interference between the secondary flow on the end wall and the flow separation on the vane surface. (2) The pressure on the suction surface recovers slightly even in the region of separation, owing to the secondary flow. (3) The outlet flow turns into the radial direction near the design point, as expected in the cascade design. (4) The minimum flow-loss is given at a small positive incidence angle, and the mixing loss downstream of the cascade is considerable.
