| Abstract: | Taking ZA150-315 petrochemical centrifugal pump as investigation object,three kinds of its impellers C1,C2 and C3 with three different blade thickness variation pattern were constructed when the basic exterior parameters and rotational speed of centrifugal impeller were fixed. The velocity and pressure distribution of centrifugal impeller inner flow were obtained by using numerical simulation for 5 different operational conditions,respectively.Analysis of simulated results demonstrated that the efficiency o... |
