【Abstract】 A two-dimensional bottom jet discharged into a cross-flow is simulated by the standard two-equation k-ε model with VOF method. By comparing with experimental results, it is shown that the recirculation zones calculated using the model generally agree with the experimental results. Velocity and concentration’s trajectories are expressed by simple formulas and compared with experimental results. Some conclusions are also draw by analyzing the velocity and concentration distributions.更多还原
