This paper investigates 3D simulation of fluid flow in a centrifugal pump from the Detroit Diesel company to extract possible engine cooling trends.  The velocity and pressure profile of water, the coolant, is analyzed and the characteristic curves of the pump are derived. This provides a useful evaluation of the pump performance at all working conditions. For this aim, a computational fluid dy...

Effects of the time-variant flow in a single-blade pump are investigated by numerical and experimental methods. For a numerical approach the three-dimensional, viscous, unsteady flow field in the pump has been achieved by solving the unsteady Navier-Stokes equations (URANS) with a commercial solver. From the obtained periodic flow field the time-variant forces acting at the wetted impeller surf...

Centrifugal pumps are widely used in the oil and mining industries. In contrast to water pumps, centrifugal industries for transportation of drilling fluid, which is typically non-Newtonian fluid. Drilling fluids usually modeled as power-law with varying shear viscosity imposed rates. this paper, a numerical simulation fluid flow pump was simulated, only flow-rate magnitude, using comparison. T...

The following scenarios explore some of the common problems encountered during extracorporeal membrane oxygenation (ECMO) in adults. In each scenario, the circuit is comprised of a centrifugal pump and a polymethylpentene oxygenator.

The electric submersible pump (ESP) is a centrifugal with several stages. It's dependable and efficient industrial lifting tool for different amounts of fluids, it's known its adaptability reliability.

In the present study, multi-objective optimization of centrifugal pumps is performed at three steps. At the first step, η and NPSHr in a set of centrifugal pump are numerically investigated using commercial software. Two meta-models based on the evolved group method of data handling (GMDH) type neural networks are obtained, at the second step, for modeling of η and NPSHr with respect to geometr...

Modeling and multi-objective optimization of centrifugal pumps is performed at three steps. At the first step, η and NPSHr in a set of centrifugal pump are numerically investigated using commercial software NUMECA. Two metamodels based on the evolved group method of data handling (GMDH) type neural networks are obtained, at the second step, for modeling of η and NPSHr with respect to geometrica...

In Egypt, surface irrigation is the most commonly used method comparing with the other irrigation systems in old land. In addition, centrifugal instruments are prevailing used for irrigating fields. However, the major problem who confronts the farmers at operating these instruments is priming it to be operating by filling the water to replace the air in pipes. To be prime the instrument need tw...
