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.

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.

Scale Effects in a Mixed Flow Pump: Part 1
Proceedings of the Institution of Mechanical Engineers, Part A: Power and Process Engineering, 1986The variation of efficiency and losses over a range of Reynolds numbers has been measured for a mixed flow pump of specific speed 118 r/min for a number of points covering its operating range. The losses have been separated into those of the impeller and volute.
