Numerical Modeling of the Penetration Area of Submerged Jet by the method of finite element

Water jet flow has many usages in the field of management and water resource operation that can be applied in mixing, dilution and aerification. The current study has calculated the flow velocity, length and height of jet penetration area ( the jet and main flow are of opposite directions) by the use of finite element method and k-ε model. In order to evaluate and verify this turbulent model, the results of the numerical model have been compared with the experimental results. This model has been studied for more consideration of various jet flow velocities and thicknesses. The conclusions have indicated that the length and height of the penetration area have linear relationship with jet flow velocity; therefore, as the jet flow velocity increases, the length of jet penetration increases as well. The comparison of the results of numerical method with the experimental data have demonstrated that this method holds an acceptable and powerful predictability
