Experimental study and numerical simulation of internal flow dissipation mechanism of an axial-flow pump under different design parameters.

This research uses CFD (computational fluid dynamics) to simulate an axial-flow pump and analyzes its internal flow dissipation. The results show that under different operating conditions, with increasing tip cascade density, the pump head gradually increases. With increasing tip cascade density, the pump efficiency gradually decreases under small discharge conditions, and the high-efficiency zone of the axial-flow pump gradually narrows when the pump is operated under large discharge conditions.
