number turbulence models were analyzed. The simulated results of YANG-SHIH model are close to the large eddy simulation results and experimental results, and they are significantly better than those of ABE-KONDOH-NAGANO, ABID and LAUNDER-SHARMR models. The modification of the generation of turbulence kinetic energy is the key factor to a successful simulation for YANG-SHIH model, while......

speed, the submerged depth and the downward angle of the nozzle. A numerical simulation of the hydraulic model was carried out trying to find the suitable turbulence model which can describe the side... depth and the surface fluctuation height are reduced. It is concluded that the numerical results with the realizable k-ε turbulence model are the closest to the experiment for the penetration depth......
