Numerical Simulation of Flow Pattern around the Bridge Pier with Submerged Vanes
Bridges are very important for establishing communication paths. For this reason, it is important to control scour around bridge piers. Several methods have been proposed for scour control. One of the most useful methods is the use of submerged vanes. In the other hand, laboratory circumstances force many considered effective factors to be skipped in the scour phenomenon. In this situation, the...

متن کاملExperimental comparison of sacrificial piles and submerged vanes as scour countermeasures around bridge pier
An experimental study has been conducted on the effectiveness of two types of flow-altering countermeasures placed around a cylindrical pier under clear water condition, which include sacrificial piles and submerged vanes. Their arrangements follow the optimal configurations recommended in the published articles with some modification. The temporal evolution of maximum scour depth and its equil...
متن کاملsimulation of flow pattern around inclined bridge group pier using flow-3d software
introduction: bridges are certainly one of the most important structures but costly service elements in a transport system. the bridges are very required to access the damaged areas in emergency situations such as floods and earthquakes. scour around the foundations of bridge piers exposed to the flowing water than can destroy the bridge itself is a subject of major concern. flow pattern is kno...
متن کاملبررسی عددی سه بعدی الگوی جریان و تنش برشی بستر اطراف پایه های مخروطی
Investigation of the flow pattern around bridge piers is of utmost importance because of its great effect on destruction of the piers. Despite the hydrodynamical and structural values of designing sections causing minimum turbulence against the flow passing the bridge pier, a review of the literature shows that investigation of the flow pattern around bridge piers with varying section has not b...
