| Abstract: | The direct axisymmetric problem of the theory of hydrodynamic machinery is considered for flows in the turbine and pump regimes. In formulating and numerically solving the problem the conditions at the edges of the blade systems 7, 8] expressing the principal conservation laws are taken into account. The three-dimensional pressure distribution in the blade systems is calculated using the asymptotic relations 1, 9]. The results of the calculations are presented and the theoretical and experimental data on the flows in the blade passages of high-speed pump-turbines are compared.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No, 4, pp. 12–19, July–August, 1988. |
