基于已设计的同一液体射流泵试验装置,采用脉冲和恒定工作液体射流,应用数值计算方法研究了脉冲与恒定液体射流泵基本性能方程的参数,并定量分析了流速比M、动量修正系数k1与k2随面积比的变化规律及其对液体射流泵性能的影响,提出了优化结构、率定几何参数的建议。 Based on the same experimental design of liquid jet pump, the pulse and constant working liquid jet are used to study the parameters of the basic performance equation of pulse and constant liquid jet pump by numerical calculation. The relationship between flow velocity ratio M, momentum correction coefficient k1 and k2 as a function of area ratio and its effect on the performance of the liquid jet pump, put forward the suggestion of optimizing the structure and setting the geometric parameters.
