Abstract

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 Fr1=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-, Renormalization-group k-ε and Realizable k-ε turbulence closure models are employed. Experimental validations of the numerical results show that computations using Renormalization-group k-ε 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

Özet

Mansabında batmış hidrolik sıçramanın oluştuğu düşey bir kayar kapak içeren açık kanal modelinde, Fr1=1.77 ve 1.35 olan akımlar için su yüzü profili ölçülmüştür. Akımı idare eden denklemler, deney koşullarındaki akımlar için Sonlu Hacimler yöntemi ile sayısal olarak çözülmüştür. Sayısal modellemelerde, Standard k-, Renormalization-group k- ve Realizable k-ε türbülans kapatma modelleri kullanılmıştır. Sayısal model bulgularının deneysel olarak doğrulanmasına yönelik yapılan karşılaştırmalar, serbest su yüzü profili ve batmış hidrolik sıçrama geometrisinin belirlenmesinde Renormalization-group k-ε türbülans modelinin diğer ikisine göre daha başarılı olduğunu göstermiştir
