Abstract:

The design point performance of shear force pumps is compared with that of conventional pumps in terms of the similarity parameters specific speed, specific diameter and suction specific speed. Using arguments of the cascade theory, the maximum suction specific speed potential of conventional pumps is calculated for conventional as well as sophisticated blade design concepts. Comparing these data with experimental and theoretical data of shear force pumps, it was demonstrated that shear force pumps can obtain about 10 to 20 times higher suction specific speeds than conventional pumps in the medium specific speed regime, but that the efficiency potential of shear force pumps is lower than that of conventional pumps. The high suction specific speed potential of the shear force pump can be used advantageously in the design of compact lightweight space power plants. Author
