This paper introduces the hydrodynamics theory related to water wave pump. Water wave pump is a new type pump, which uses the particular quality of water wave and re-divides the inflow energy to increase the pressure of one part of the inflow water with the rest water flowing away freely. The research and development of such a pump is of importance and significant value and profitable social interest in that it can fully utilize the residual energy of natural source in industrial and civil water circle systems. Through hydrodynamics research and calculation, a series of valid design parameters were obtained and the predicted results achieved. 展开更多
