Abstract
The velocity field and surface profile of an open channel flow with a submerged hydraulic jump from a vertical sluice gate are investigated for two different flow cases. The governing equations are numerically solved using a finite-volume method for flows having the same conditions with experiments. The volume of fluid method is used to calculate the free surface. In modeling the turbulence stresses, standard , renormalization group , realizable , shear stress transport , and Reynolds stress turbulence closure models are employed. A grid convergence index analysis is carried out to determine the discretization error for the grid-independent solution. Experimental validations of the numerical results show that in predicting the velocity field, the Reynolds stress turbulence model is the most successful among the five. It also estimates the free-surface profile of the flow successfully.
