Hydrodynamics of Pumps
TL;DR: In this article, the authors focus on the design issues associated with the flow of liquid through a rotating machine and the potential for cavitation and the high density of liquids that enhances the possibility of damaging unsteady flows and forces.

Numerical Simulation of the Dynamic Effects Due to Impeller-Volute Interaction in a Centrifugal Pump
TL;DR: In this article, a numerical simulation of a commercial centrifugal water pump with backward curved blades is presented, where the viscous Navier-Stokes equations are handled with an unsteady calculation and the sliding mesh technique is applied to take into account the impeller-volute interaction.
Journal ArticleDOI
Numerical and Experimental Investigations of the Cavitating Behavior of an Inducer
TL;DR: In this paper, a robust CFD model for general three-dimensional flows with extensive cavitation at large density ratios is described, which utilizes a multiphase approach based on volume-scalar-equations, a truncated RayleighPlesset equation for bubble dynamics, and specific numerical modifications (in a finite-volume solution approach) to promote robust solutions when cavitation is present.

Investigation into pressure pulsations in a centrifugal pump using numerical methods supported by industrial tests
R. Spence,J. Amaral-Teixeira +1 more
TL;DR: A numerical investigation of the time variation of pressure within a complete centrifugal pump was undertaken and transient flow results compared reasonably with experimental data obtained in a limited experimental survey and clearly indicated the pump locations experiencing the largest pulsation levels.

Numerical analysis of unsteady tip leakage vortex cavitation cloud and unstable suction-side-perpendicular cavitating vortices in an axial flow pump
TL;DR: In this paper, the formation of three-dimensional tip leakage vortex (TLV) cavitation cloud and the periodic collapse of TLV-induced suction-side-perpendicular cavitating vortice (SSPCV) were analyzed.
