rotating stall inception impacted by tip leakage vortex and inlet unsteady flow in a mixed-flow …

In this study, a comparative analysis of the shutdown transitions of a full-flow pump and an
axial-flow pump was carried out through numerical simulation and model tests. The UDF …

In this study, we analyze gas–liquid interaction characteristics using a heterogeneous two-
fluid model to investigate the influence of interphase force on multiphase pump …

Cavitating flow is extremely complex in axial and mixed flow pumps, resulting in several
adverse effects on pump performance. In this paper, the tip leakage vortex (TLV) cavitation …
