Noise sources in centrifugal pumps
- Proceedings of the 2nd WSEAS Int. Conference on Applied and Theoretical Mechanics
, 2006
"... Abstract:- The reduction of noise emission is of vital importance for pumps used in HVAC applications. Several components contribute to the noise emission of a pump, e.g. pressure pulsations originating from the hydraulics or electromagnetic forces in the electrical drive. In order to reduce the noi ..."

Detection of Cavitation in Centrifugal Pumps
, 2011
"... Abstract: Pumps are designed and manufactured to operate well away from the cavitation condition and thus the factors affecting the onset of cavitation are important. A specially designed test rig was and constructed so that the onset of cavitation could be studied visually while obtaining actual N ..."

"... Variable-speed control of centrifugal pumps is an effective energy conservation method. This method requires substantial investment, which must be justified by energy saving. A popular method for energy saving estimation is the use of the well-known affinity laws, which imply that power input varies ..."

CAVITATION CFD IN A CENTRIFUGAL PUMP
"... The cavitation flow in a low specific centrifugal pump is analyzed by using two types of cavitation CFD codes. A locally homogeneous model of compressible air-vapor-liquid two-phase medium is applied to calculate the objective flow. Constant Enthalpy Vaporization model is also applied. Numerical res ..."
