Abstract

A flow model was proposed to compute the fluid pressure in pump side chamber. Based on which the flow can be regarded as a secondary and axisymmetric viscous laminar flow, which is the superposition of circumferential shear flow and radial differential pressure one. These were described using N-S equations. By comparing orders of magnitude, the N-S equations were simplified. They were then integrated to obtain the analytical solutions. The correction coefficient of potential head was introduced to determine simplified computation model for fluid pressure inside chamber. By ignoring the influence of leakage, the final computation model was established. This research used the model to predict the pressure profiles of a centrifugal pump and the theoretical profile agrees well with the experimental one.
