【摘要】 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。
【Abstract】 Based on the steady and pulsed liquid jet in the same jet flow pump experimental apparatus,the performance parameters of time-average basic performance equation of steady and pulsed liquid jet flow pump are studied with numerical methods.The change laws of velocity ratio M,momentum correction factor k1 and k2 with the area ratio and influence to performance are quantitatively analyzed.The suggestion is proposed that its structure should be optimized and geometric parameters should be calibrated.
