A DDES-Driven Framework for Hydraulic Radial-Force Reduction in Centrifugal Pumps via Sensitivity Analysis and Surrogate-Based Optimization

Hydraulic radial force from rotor–stator interaction causes pump vibration and bearing wear. To regulate this, this study proposes a low-vibration impeller design framework combining delayed detached-eddy simulation (DDES), Spearman correlation, sensitivity analysis, and multi-objective NSGA-II optimization, while expl...
