A mixed-flow impeller with a specific speed of 750 (m^3/min, m, rpm) was chosen as a prototype. Quasi three-dimensional potential flow analysis was conducted on the impeller, and three partial impellers having casing geometries equal to 3/4, 2/4 and 1/4 flow-rate meridional stream lines of the prototype impeller were further introduced. The performance of fans with these four impellers was measured and compared with each other. Since they are identical from the view point of potential flow, all differences in performance can be attributed to the viscous effect.
