Abstract: A
k-e-Ap model is used to simulate two-phase turbulent flow, and
pressure-correction equation is achieved to couple the continuity
equation and the momentum equations according to SIMPLEC. Thus
time-averaged governing equations of which are developed. On the basis
of the GEMCHIP algorithm, a program to calculate the internal flow
within the pump impellers is designed, and the calculating results are
displayed into some figures. The simulated results exhibit: there exist
a jet-wake structure around the shroud-suction side area, and a relative
velocity slip between the solid and liquid which de-creases gradually
along the passage.
