Numerical Study on throat tube inlet function of Pulsed Liquid Jet Pump

摘要

In this paper, the performance parameters of time-average basic performance equation of pulsed liquid jet pump are studied in numerical methods. The change rules and its influence on performance of throat tube inlet function are quantitatively analyzed. The conclusion is obtained that pulsed jet could mainly make fluid of throat tube outlet more fully mixed and better improve optimal working parameters of liquid jet pump. Also, change rules of throat tube inlet function show the increasing of the entrainment rate is the reason why pulsed liquid jet pump could improve performance.
