A three-dimensional mathematical model for calculating the steady flow of circular non-buoyant turbulent surface in a coflowing channel is presented in this paper.For closing the control equations,the κ-ε turbulence model is used in the mathematical model.The wall-function method is employed to treat the wall boundary condition at the bottom plane.The closed control equations are discretized by using Hybrid Finite Analytic Method(HFAM)on a non-uniform staggered grid system.The numerical results are obtained for different ratio of the jet velocity to the coflowing velocity.The comparison with experimental data shows good agreement.
