Abstract

Purpose: The purpose of this study is to explore the transient characteristics of mixed-flow pumps during startup process. Design/methodology/approach: This study uses a full-flow field transient calculation method of mixed-flow pump based on a closed-loop model. Findings: The findings show the hydraulic losses and internal flow characteristics of the piping system during the start-up process. Research limitations/implications: Large computational cost. Practical implications: Improve the accuracy of current numerical simulation results in transient process of mixed-flow pump. Originality/value: Simplify the setting of boundary conditions in the transient calculation.
