A Numerical Analysis of a Mixed Flow Pump
Volume 2: Symposia and General Papers, Parts A and B, 2002The rotating passages of turbomachinery contain some very interesting and complex fluid flow phenomena. This paper presents the three-dimensional turbulent flow through the impeller passages and surroundings of a mixed-flow pump. The model has five impeller blades mounted on a conical hub and nine stator blades in a diffuser which brings the diagonally

Performance prediction of mixed-flow pumps
Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 1998This paper presents the mean streamline analysis using the empirical loss models for performance prediction of mixed-flow pumps with high specific speeds. A new internal loss model to describe the effect of flow separation on the characteristic head-capacity curve with a dip in the low flow range is developed and a modified recirculation loss model for

Control Strategy for Biventricular Assistance with Mixed‐Flow Pumps
Artificial Organs, 2000Abstract: A left ventricular assist device (LVAD) is an effective method to rescue severe heart failure. Although some require a biventricular assist, the control method for the biventricular assist device (BVAD) with a rotary pump is rarely shown. The objective of this study was to investigate the strategy for controlling BVAD with rotary pumps by in ...

High-efficiency design of a mixed-flow pump
Science in China Series E: Technological Sciences, 2010High-efficiency design of a mixed-flow pump has been carried out based on numerical analysis of a three-dimensional viscous flow. For analysis, the Reynolds-averaged Navier-Stokes equations with a shear stress transport turbulence model were discretized by finite-volume approximations. Structured grid system was constructed in the computational domain,

Hydraulic Performance of a Mixed-Flow Pump: Unsteady Inviscid Computations and Loss Models
Journal of Fluids Engineering, 2001The hydraulic performance of an industrial mixed-flow pump is analyzed using a three-dimensional potential flow model to compute the unsteady flow through the entire pump configuration. Subsequently, several additional models that use the potential flow results are employed to assess the losses.
