Abstract: | The equations of the problem of calculating secondary flows in hydromachinery blade systems are obtained for the quasi-three-dimensional flow approximations. The results of calculating these flows for a Francis turbine and the pumping regime of a pumpturbine are presented.Translated from Izvestiya Rossiiskoi Akademii Nauk, Mekhanika Zhdkosti i Gaza, No. 5, pp. 10–15, September–October, 1993. |
