摘要
针对准三元反命题设计方法中不易给出合理的rVθ子午流面分布问题,本文在用流线曲率法进行半反命题设计的基础上,考虑了一定的气动力学条件,通过求解方程得到rVθ子午流面分布的方法,编制了准三元反命题设计程序,并给出了一个离心叶轮气动设计算例,计算结果表明了本文程序的可行性和合理性.
In this paper, aiming at the difficulty of giving a reasonable distribution of the mean swiri rVθ on the meridional streamsurface, a method of giving the distribution of rVθ is pro-posed in quasi-three dimensional inverse aerodynamic design adopting the streamline curva-ture method, which considers certain aerodynamic conditions and calculates the distribution by solving an equation. On the base, a computer program is compiled for quasi - three dimensional inverse aerodyunamic design. With the program, a centrifugal impeller is de-signed. The design result showr that the program is applicable and reasonable.
