Free surface flows past surfboards and sluice gates
Free surface potential flows past surfboards and sluice gates are considered. The problem is solved numerically by boundary integral equation methods. In addition weakly nonlinear solutions are presented. It is shown among the six possible types of steady flows, only three exist. The physical relevance of these solutions is discussed in terms of the radiation condition (which requires that ther...
متن کاملComparison of Experimental Study and Cfd Analysis of the Flow under a Sluice Gate
Flow in the open channels has great importance in the hydraulic engineering. Any disturbances as contractions and expansions affect the flow characteristics like velocities, flow rates and water surface profiles. Their effects on the flow must be considered during the design process of flow structures. In the last decades numerical solutions become popular as experimental studies take time, may...
متن کاملApplication of improved neuro-fuzzy GMDH to predict scour depth at sluice gates
An improved neuro-fuzzy based group method of data handling using the particle swarm optimization (NF-GMDH-PSO) is developed as an adaptive learning network to predict the localized scour downstream of a sluice gate with an apron. The input characteristic parameters affecting the scour depth are the sediment size and its gradation, apron length, sluice gate opening, and the flow conditions upst...

متن کاملEffects of Multi-gates Operations on Bottom Velocity Pattern under Submerged Flow Conditions
Failures of barrages or regulators or parts of them may be expected when excessive scour patterns are observed downstream of such structures. Severe and excessive scour may be largely due to unsymmetric operation of gates especially when a multi-vents barrages or regulator is being considered. Previous investigations proved that the scour patterns downstream hydraulic structures are functions o...
