A numerical flow simulation of a mixed flow pump [PDF]
, 2002 Mixed flow pumps are primarily axial flow pumps, but they impart some degree of radial and swirling momentum to the pump fluid as it passes through the rotor section. They are popular for pumping water in tight spaces, so are used for residential wells, municipal water works, industrial applications, and even for powering small water craft.

Dynamic Characteristics of Rotating Stall in Mixed Flow Pump [PDF]
Journal of Applied Mathematics, 2013 Rotating stall, a phenomenon that causes flow instabilities and pressure hysteresis by propagating at some fraction of the impeller rotational speed, can occur in centrifugal impellers, mixed impellers, radial diffusers, or axial diffusers.

Large-Eddy Simulation of Unsteady Flow in a Mixed-Flow Pump [PDF]
International Journal of Rotating Machinery, 2003 This article describes the large-eddy simulation (LES) of the internal flows of a high–specific-speed, mixed-flow pump at low flow-rate ratios over which measured head-flow characteristics exhibit weak instability. In order to deal with a moving boundary

The Influence of a Pumping Chamber on Hydraulic Losses in a Mixed-Flow Pump [PDF]
Processes, 2022 In this study, entropy generation theory based on computational fluid dynamics (CFD) is used to study the influence of a pumping chamber type (guide vane and volute scheme) on the spatial distribution of hydraulic loss in a mixed-flow pump. The CFD data of the mixed-flow pump with a volute is validated by external characteristic test data under Q = 561.
