Özet

Experimental and Numerical Modeling of Submerged Hydraulic Jump Downstream of a Sluice Gate The flow profile in an open channel model with submerged hydraulic jump downstream of a vertical sluice gate is measured for flow cases with Fr-1=1.77 and 1.35. The governing equations are numerically solved using Finite Volume method for the flows having the same conditions with experiments. In the numerical simulations, Standard k-epsilon, Renormalization-group k-epsilon and Realizable k-epsilon turbulence closure models are employed. Experimental validations of the numerical results show that computations using Renormalization-group k-epsilon turbulence model are the most successful, among the three, in predicting the free surface of the flow and the geometry of the submerged hydraulic jump.
