Computational Study of low Specific Speed Centrifugal Pump Impeller

Recently, a centrifugal pump in the range of very low specific speed, such as ns 0.25, attracts attention as a substitute for positive displacement pump because not only of vibration and noise problem but also due to recent demand towards small size and high rotational speed it is now inevitable to develop a new centrifugal pump with high performance in very low specific speed range. The present work for the project includes the study of pressure and velocity variation along the blade of different type (D and E type), flow pattern at inlet and outlet of runner. To plot the drop curve of both impeller. Based on available data from literature review developed computational model of two semi open impeller D and E.
