3D Numerical Simulation in Inlet Passages of Pumping Station by RNG k-ε Turbulent Model with Wall-function Law

Pumping station inlet is an important part of the pumping station.The RNG k-e turbulent model with wall-function law is firstly applied to simulate the inlet passages of pumping station.The incompressible N-S equations are solved by the finite volume method with a staggered grid in a non-orthogonal curvilineal system.The optimum function of inlet passage is proposed,and the numerical loss of head is given.A good agreement is achieved between prediction data and experience data.The RNG k-e turbulent model with wall-function law can be used to simulate flow and loss of head in the passages of the pumping station.
