| Abstract: | Taking account of the loss inside a vane wheel, optimization technique isapplied to the numerical computation of flow type for meridionally-accelera-ted axial-flow fans on the basis of analyzing the stage-efficiency equation.The optimum flow type so determined is compared with the data measured ofcommonly-used flow type in current fan design for their different influences onfan's performance. |
