Abstract

this paper presents experimental analysis results and Computational Fluid Dynamic (CFD) analysis of a water jet pump. The effect of modifying area ratio has been studied experimentally and numerically. A test rig has been planned to study the jet pump several parts using different dimensions and forms, to give more than one area ratio of the jet pump. The style of Computational Fluid Dynamic provides an origin for quantifying the consequences of operating circumstances on the pump performance. During this article, the performing measurements are administered for four motivating pressures 1, 1.5,2, and 2.5 bar, also three values of area ratio are used, they're area ratio = 0.19, 0.29 and 0.41. The results illustrate and discuss velocity and pressure profiles. The worth of area ratio which provides the highest efficiency was found to be 0.19. The Computational Fluid Dynamic results were found to agree well with actual values obtained from the experimental results.
