【摘要】 作者研究了n_s=66的50-32-125低比速离心泵蜗壳中的流动,用有限元方法计算了蜗壳中的流场,特别是隔舌附近的流场;并且应用示踪粒子配合高速摄影的方法对计算进行了检验。计算与试验结果比较,符合得较好。更多还原

【Abstract】 In the paper, fluid flowing in volute of low specific speed centrifugal pump with n = 66, type 50-32-125, had been researched and the flowing field in volute had been calculated with FEM, especially the flowing field nearby cu-ttongue. Otherwise, by means of tracing particles with smear photography camera to examine the calculation had been disccussed. It is good identity of comparing the results of calculation with smear photography.更多还原
