Unsteady Flow Behavior and Radial Force Analysis of a Side Channel Pump Under Different Blade Tip Cutting Angles Using Computational Fluid Dynamics

Energy Science &Engineering, EarlyView.
The Radial Force (RF) distribution under different cutting angles is presented in Figure 1. Generally, the distribution of RF displays divergence across different flow conditions. The pattern of force distribution reveals a total of 24 peaks, which corresponds to the number of blades of the impeller of the SCP.
