Study on fundamental performance of pulsed liquid jet pump

本文根据脉冲液体的动量方程和能量方程， 导出了脉冲液体射流泵基本性能方程， 并与恒定流的液体射流泵基本性能方程进行了对比， 阐明了二者之间的关系． 依据脉冲液体射流泵时均值性能试验数据和其几何尺寸， 经分析与计算给出了脉冲液体射流泵时均值基本性能的经验公式．

Based on the momentum and energy equations of the pulsed liquid, the fundamental performance equation of the pulsed liquid jet pump is derived and compared with the equation for steady liquid jet pump. According to the experimental data of the time averaged performance and the geometric size of the pulsed liquid jet pump, an empirical formula for the fundamental performance of this kind of pump is proposed.
