Abstract
Centrifugal pumps are designed and manufactured in order to be fitted to
installations and work over a wide range of operating conditions. In such cases
the prediction of performance constitutes an important challenge for the pump
designer. The challenge becomes particularly difficult when it is necessary to
predict the performance of different types of centrifugal pumps varying from low
to high volume flow rates. Even if one possesses the rig to measure the
performance of a pump, it is useful and time saving to predict numerically the
overall pump characteristics. The present method is a simple and easy to apply
numerical tool for pump performance curve estimation. It requires a minimum of
pump geometrical data and it can be advantageous to pump designers providing
them with an initial performance curve estimation during the design process,
before they advance to the detailed design of the pump and its experimental
verification on the test rig. From the cases examined, it is concluded that the
proposed method provides a satisfactory approximation of industrial centrifugal
pumps’ performance curves, constituting a potential tool for pump
manufacturers.
Keywords: performance curve, characteristic line, centrifugal pump, numerical
prediction.
