Investigations of Rotational Speed and Flow Rate on Centrifugal Pump Performance Using CFD
Fluent is a professional CFD software, which is used to simulate and analyze fluid flow and heat exchange problems in complex geometric areas. It can accurately describe the internal flow field situation of the centrifugal pump model. The velocity and pressure distribution of the fluid in the centrifugal pump are obtained through the numerical simulation of the internal flow field in the centrifugal pump under the set rated and variable working conditions. Since one of the parameters that this experiment is working on, the rotating speed of the centrifugal pump was limited to a few certain values for the purposes of determining the head, power and pump efficiency when varying other parameters such as mass flow rate. Efficiency of centrifugal pump is calculated by the power output divided by power input. Power output can be calculated based on the density, gravitational acceleration, mass flow rate and pump head. Power input is calculated by moment and rotational speed. Mass flow rate is also an important parameter when determine the efficiency of the centrifugal pump. Based on the analysis and calculations above, several conclusions have been drawn regarding the mass flow rate, rotational speed, power and efficiency.
