Solid-liquid two-phase flow and wear analysis in a large-scale centrifugal slurry pump

, 2020
Centrifugal slurry pumps are widely used in the mining and dredging industries. However, the flow passage components in the pump can become severely worn due to their low speeds, high flow rates, and high slurry concentrations.

Microaxial Flow Pump or Standard Care in Infarct-Related Cardiogenic Shock.

New England Journal of Medicine
BACKGROUND The effects of temporary mechanical circulatory support with a microaxial flow pump on mortality among patients with ST-segment elevation myocardial infarction (STEMI) complicated by cardiogenic shock remains unclear.

Theoretical model of energy performance prediction and BEP determination for centrifugal pump as turbine

Energy, 2019
Pump as Turbine (PAT) is an effective alternative of power generation for small hydropower system. Since the characteristic curves under turbine mode are not supplied by manufacturer of pumps, the theoretical model for energy performance of centrifugal ...

Tip clearance on pressure fluctuation intensity and vortex characteristic of a mixed flow pump as turbine at pump mode

Renewable Energy, 2018
The present work investigates the pressure fluctuation intensity and vortex characteristic of a mixed flow pump as turbine at pump mode with a tip clearance. The tip clearance between the blade tip and shroud can induce tip leakage flow and interact with

Pumps and Pumping

1994
Pumps are used widely in aquaculture, and their initial purchase price and operation and maintenance costs are major expenses in many aquaculture enterprises. Pumps are mechanical devices that impart mechanical energy to water to lift and pressurize while overcoming energy losses during conveyance of water.

On a Pump

Acta Applicandae Mathematicae, 2005
The goal of this paper is to analyze the issue of existence for a model of the 2D motion of an incompressible viscous fluid in a domain with moving boundaries governed by the Navier-Stokes equations with slip boundary conditions admitting flows across the boundary. The subject is connected to problems for the Navier-Stokes equations with nonhomogeneous

Symmetrical and unsymmetrical tip clearances on cavitation performance and radial force of a mixed flow pump as turbine at pump mode

Renewable Energy, 2018
Transient cavitating flows of a mixedflow PAT (pump as turbine) at pump mode are investigated experimentally and numerically. Radial force on principal axis is recorded and compared between pump with symmetrical and unsymmetrical tip clearance. Numerical
