摘要：

In the theory of radial-flow hydraulic machines presented in our former paper, the expansion into Fourier series of the velocity component normal to a rotor blade plays a fundamental role. In the present paper it is shown that the coefficients of this series can be expressed by exact closed formulae. This property makes it possible to reduce considerably the time needed for computation of flow around the rotor as well as to increase the overall accuracy of the computations.
