CFD Predictions of Dense Slurry Flow in Centrifugal Pump Casings
Dense slurry flow through centrifugal pump casing has been modeled using the Eulerian-Eulerian approach with Eulerian multiphase model in FLUENT 6.1. First order upwinding is considered for the discretization of momentum, k and ε terms. SIMPLE algorithm has been applied for dealing with pressurevelocity coupling. A mixture property based k-ε turbulence model has been used for modeling turbulenc...
متن کاملDevelopment of Linguistic Rules Diagnosis of Failure in Centrifugal Pump for Use in Expert System
Operational failures in centrifuge pumps could be hydraulic or mechanical. However, most of these mechanical and hydraulic failures are connected cause of their operational nature and finding the right cause is due to considering numerous mechanical and hydraulic signs and parameters in pumps. On the other hand, due to non-linear and fluctuant behavior of pumps in the matter of time and not pre...

15 صفحه اولA Cfd Analysis of Centrifugal Pump to Improve Discharge by Varying Blade Geometry
Centrifugal pumps are used in cooling the engine by pumping water as coolant into the engine. The normal function of the coolant is to discharge coolant at a specific velocity into the engine coolant volume, once the coolant crosses 150 C temperatures then it is taken to the radiator for cooling to 50 C. Due to changes in the engine design it is desired to have changes in the centrifugal pump d...
