In this paper, a full-dimensional inverse problem calculation method is proposed, which decomposes the velocity into the circumferential average and periodic fluctuation components. The Fourier transform is used to transform the full three-dimensional problem into several two-dimensional problems. And the effect of leaf thickening, and is applied to the design of the rotor of the vane adjustable mixing pump. The calculation shows that the method can be used for the optimization design of such pumps.
