Numerical Study on Performance Parameter of Pulsed Liquid Jet Pump

The performance parameters of time-average basic performance equation of pulsed liquid jet pump are studied innumerical methods. Optimal working parameters, change law and influence on performance of momentum correction factor, throat tube inlet function are quantitatively analyzed. The conclusion is obtained that pulse jet could mainly make fluid of throat tube outlet more fully mix and optimal working parameters of liquid jet pump better improve. Also, change law of throat tube inlet function shows the reason why pulse liquid jet pump could improve performance, mainly to increase the entrainment rate.
