Cooling design of an aero-engine fuel centrifugal pump at shut-off

Numerical Study of the tongue geometry effects on the cavitation and performance of a centrifugal pump in off-design conditions

In this study, the effects of the volute tongue geometry variation on the head, efficiency, velocity distribution and cavitation structure of a centrifugal pump in the steady flow behavior under off-design conditions have been investigated. Numerical simulation modeling based on the  turbulence model with a hybrid grid is used to simulate the flow within the modeled pump. The flow is simulated ...

Design, Manufacturing and Tests of an Implantable Centrifugal Blood Pump

An implantable centrifugal blood pump was developed for longterm ventricular assistance in cardiac patients. In vitro tests were performed, as wear evaluation, performance tests and hemolysis tests in human blood. Numerical computational simulations were performed during design process in order to predict its best geometry. Wear evaluations helped to select the best materials for double pivot b...

Design and Performance Analysis of Centrifugal Pump

This paper deals with the design and performance analysis of centrifugal pump. In this paper, centrifugal pump is analyzed by using a single-stage end suction centrifugal pump. Two main components of a centrifugal pump are the impeller and the casing. The impeller is a rotating component and the casing is a stationary component. In centrifugal pump, water enters axially through the impeller eye...

Centrifugal Pump Cooling and Lubricant Application— a “best Technology” Update

Process pumps experience widely different operating times to failure. U.S. refineries achieve pump mean-times-between-failure (MTBFs) ranging from less than three years to in excess of eight years. While the importance of pump hydraulic design seems well understood, insufficient attention has been given to important issues of bearing lubricant selection, protection of the oil against contaminan...
