Optimum time to refurbish a boiler feed pump at Eskom's power stations [PDF]
A key focus area in power generation today is to improve equipment and plant efficiency, with this study specifically aimed to determine the optimum time to refurbish a boiler feed pump by analysing the internal wear of the annular seals. The boiler feed

Numerical Prediction of Performance of Annular-Type Jet Pump.
Jet pumps are used in a great number of engineering applications. However, no numerical method for determining the performance has been established yet. In the present study, focusing on turbulence models, a numerical method for predicting the performance of an annular-type jet pump is investigated. The flow fields are simulated by solving Reynolds and

The importance of the knowledge of flow stream in water sump pump [PDF]
Numerous different experimental and numerical methods have been developed and are already improved in order to get rather good flow descriptions inside pump components. These calculations are generally realized assuming uniform and steady flow conditions,
