Abstract: Hydromechanics theory concerning with water pumps is proposed. Water wave pump combines the functions of Air Wave Charger and Water Hammer Pump to show fine performance, where the total energy of inflow is redistributed to heighte n the presure of a part of the the flow to the desired level whereas for therest of flow a low level of pressure is maintained, which causes moving water with high energy to reach to a higher place. On the basis of the working principles of water hammer pumps, water hammer motive power with applications is investigated, a series of parameters for water wave pump design are proposed. The computat ional results verified the validity and flexiblility.
Keywords: water wave theory, one-dimensional unsteady flow, water hammer pumps, hydromechanics calculation.
