摘要

摘要: 基于一元流动的子午面形状校核原理，研究出等腰梯形设计法。该方法依托3D软件，经过9步骤，方便快捷设计出子午面形状。将等腰梯法设计的子午面形状，与Vista RTD设计的进行比较，形状非常吻合，误差最大值在5%左右。结果表明：两个模型气动性能无明显差异，在输出功、压比、等熵效率方面，新方法的模型略优于Vista RTD的模型。

Abstract: According to the principle of one dimensional flow, we present a new method named isosceles trapezoid design method to get 3D the acceptable meridional profile in 9 steps. Comparing both meridional profiles designed respectly with the proposed method and with Vista RTD, we obtain the error to be about 5%. And the analysing results obtained with CFX show that there is no obvious difference between the aerodynamic performances of the two models. Finally the conclusion can be drawn that the isosceles trapezoid design method is feasible for designing the meridional profile on impeller.
