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 ...

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 ...

Predictive Erosion Model for Mixed Flow Centrifugal Pump
Journal of Energy Resources Technology, 2019Electrical submersible pumps (ESPs) are widely used in upstream oil production. The presence of a low concentration solid phase, particle-laden flow, in the production fluid may cause severe damage in the internal sections of the pump which reduces its operating lifetime.

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

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,

Radial forces of waterjet propulsion mixed-flow pump
Journal of Drainage and Irrigation Machinery Engineering, 2012Fluctuations of fluid pressure in hydraulic machinery can cause resonance and fatigue da-mage of blades. In order to study fluid-induced forces, which are caused by impeller-diffuser interaction, unsteady radial forces due such an effect was conducted in a mixed-flow pump with a vaned diffuser by using CFD computation and model experiment.
