CFD Simulation of Open Channel Flooding Flows and Scouring Around Bridge Structures
Simulation of scour-pit formations under the bridge decks and around the bridge piers, due to sediment suspension and transport caused by flooding and pressure flow conditions, is of significant interest nowadays to computational fluid dynamics (CFD) and hydraulic researchers. From CFD perspective, analysis of bridge under various flooding conditions and impact of the drag and lift forces on it...
متن کاملinvestigation of control methods on local scouring around the bridge piers
scouring is the removal of sediment particles resulted from variations of flow pattern. local scour is considered among the reasons of instability and ultimately failure of bridges. during the past decades, different methods were proposed against local scour at bridge piers. these methods can be broadly classified into two categories: flow-altering and bed-armoring methods. each method can be c...
متن کاملeffect of collar- slot combination on the local scouring around the bridge piers
scoure is the removal of particle sediment which results variation of flow pattern. local scour is considered as one of the reasons of instability and ultimately failure of bridges.therefore, proposing some controlling methods to reduce this phenomenon is essential. in the study, effects of two types of squar and circular collar on a single cylindrical model have been investigated. in the next ...
متن کاملReducing Local Scouring at Bridge Piles Using Collars and Geobags
The present study examines the use of collars and geobags for reducing local scour around bridge piles. The efficiency of collars and geobags was studied experimentally. The data from the experiments were compared with data from earlier studies on the use of single piles with a collar and with a geobag. The results showed that using a combination of a steel collar and a geobag yields the most s...
متن کاملInvestigating Effect of Netted Collars on Scouring Around Bridge Piers Using Flow-3D
The present study used Flow-3D to investigate the effect of installing netted collars with different shapes on bridge piers. The results showed that installing netted triangular, circular, square, and rectangular collars with a hole diameter of 0.1 (d/D) reduced scouring by 49.5, 52.2, 52.7, and 56.5 percent, respectively, compared to the case with no collars. A hole diameter of 0.15 (d/D) for ...
