| 摘 要： | 推导了以往复泵为脉冲发生装置的脉冲液体射流泵准二维性能方程及其时均性能方程，导出无因次惯性水头及惯性力项便于计算的表达式，并对脉冲液体射流泵时均性能进行了数值计算，计算结果与试验数据基本吻合，将数值计算的模拟曲线与恒定液体射流泵性能曲线进行对照，证明了采用脉冲射流作为工作动力能够大幅提高射流泵的效率。 |

| Abstract: | The quasi 2D performance equations and time-average performance equations of pulsed liquid jet pump, which used reciprocating pump as impulser, were derived. The expressions of the non-dimensional inertial head and inertial force which were easy to calculate were derived. The time-average performance of pulsed liquid jet pumps was calculated, and the calculated results were coincident with experimental data. The calculated performance curves were compared with those of the steady liquid jet pump, which proved that using pulsed jet flow as working power could greatly improve the efficiency of jet pump. |
| Keywords: | pulsed liquid jet pump numerical calculation time-average performance |
