Constriction Scour In Pressurized Flow Condition (RESEARCH NOTE)
When depth of flow past a river bridge exceeds opening under the bridge, the flow under the bridge becomes pressurized. The water is directed downward and under the bridge deck, causing increase in velocity and shear stress on the bed thereby increasing bed scour. This is termed as Pressure Flow Scour. The present study investigates the phenomenon of pressure flow scour resulting from a submerg...
متن کاملNumerical Investigation of the Influence of Water Jumping on the Local Scour beneath a Pipeline under Steady Flow
Rigid-lid approximation is usually used to replace the free surface in scour simulation. The influence of the rigid lid assumption on the prediction precision of scour hole in steady flow is studied in this paper. Firstly, a local scour model was constructed based on the open sources Computational Fluid Dynamics (CFD) model OpenFOAM, where both the bed load and suspended load were considered. I...
متن کاملComparative Analysis between Observed and Predicted Contraction Scour at Bridges Abutments
Social and economic damages are the most important damages of the bridge failure. Stability problems of such structures against failure and the depth of the abutments are directly related to the amount of the adjusted scour. Economy, reliability and stability have been main concerns regarding designing abutment bridges enhanced preventing scouring. In this study a detailed comparison of the up-...
متن کاملExperimental Investigation of the Effect of Splitter Plate Angle on the Under-Scouring of Submarine Pipeline Due to Steady Current and Clear Water Condition
Submarine pipelines are appropriate method for transmission of oil and gas from sea bed. Free spans may occur due to the natural uneven seabed or by under-scouring. Vortex Induced Vibration (VIV) can happen in such free spans at high Reynolds number. Resonance occurs if the frequency of vortex shedding is close to the pipeline’s natural frequency leading to its fatigue that can break the pipeli...
متن کاملTransport of Radon in Still Water under Steady - State and Transient Conditions
The transport of Rn through sealed, horizontal 2.54 cm diameter tubes filled with still water was observed to be significantly greater than that predicted solely from molecular diffusion. The rate of Rn transport was also found to be related to the concentration of Rn in the water. A constant source of radon producing an air concentration ranging from 1.1 to 176 Bq cm was connected to one end o...
