Analysis of flow evolution mechanism in variable speed control of semi-open impeller centrifugal pump

To investigate the transient flow characteristics and flow field hysteresis mechanism within a centrifugal pump during variable speed regulation, this paper selects a double-volute, semi-open impeller centrifugal pump as the research object, through the Pro/E software modeling for centrifugal pump 3-d full port, choo...

Multi-Objective Optimization and Entropy Production Analysis of Solid–Liquid Two-Phase Flow in Centrifugal Pumps Based on Fluent—Event-Driven Execution Manager Coupling Method

In response to the severe wear of centrifugal pumps, Workbench workflow is utilized to adjust the blade inlet and outlet angles, aiming to reduce the wear of the impeller and volute of the centrifugal pump and optimize the pump’s efficiency and head. Orthogonal experiments are conducted by varying the inlet and outlet...
