Abstract
Abstract: The sewage, drainage, and chemical industries all employ centrifugal pumps, which are a typical type of pump. By adjusting the impeller exit blade width, exit diameter, and trailing edge blade angle, a computational fluid dynamics (CFD) three-dimensional simulation is performed to optimise the pressure head, efficiency, and power needed of centrifugal pumps. The head of the pump is optimised in the CFD study of the impeller to enhance the capabilities of centrifugal pumps. Rotation of the impeller varies with the rotation and mass flow rate. The geometry of the centrifugal pump impeller in this project is originally built in Solid Works, and CFD analysis is then completed in Ansys CFX. In this study, the initial dimensions of the impeller were taken from the base paper. The performance of the impeller was then assessed using the parameters Head, Power imparted to water by the impeller, and Efficiency. From the analysis, it was discovered that as the number of blades on the impeller increases, the value of head and power imparted as well as the efficiency of the impeller increases. After that, analysis was conducted while maintaining a constant number of blades at various impeller RPMs, and the results showed
