NUMERICAL SIMULATION FOR
INCOMPRESSIBLE TURBULENT FLOW IN THE IMPELLER OF SEWAGE PUMP
Abstract:
The 3-D turbulent flow in the impeller of sewage pump is
simulated. The time-averaged N-S equations and the k-ε turbulent
model is modified. The calculation is carried out in body-fitted
coordinated grid by applying SIMPLE-C algorithm. The calculated
velocity, pressure distributions of the turbulent flow in the
sewage pump are obtained for the first time, which will be
helpful for the optimal design and performance prediction of sewage pumps on the basis of flow field simulation.
