Local Scouring around a Circular Pier in Open Channel
Local scour around a cylindrical pier in a channel with an erodible bed or natural bed is a common problems in bridge or pile supported structure. The highly unsteady complex flow field around a circular pier produces scour hole mainly for the presence of vortices. The main mechanism that drives the formation and evolution of the scour hole around bridge pier is horse shoe vortex motion. In the...
متن کاملNumerical simulation of cross-flow around four cylinders by Local Domain Free Discretization-Immersed Boundary Method
In this paper, a hybrid of Local Domain Free Discretization and Immersed Boundary Method (termed as LDFD-IBM), is applied to simulate the incompressible flow over four circular cylinders in an in-line square configuration. LDFD-IBM belongs to the family of "Cartesian mesh methods", which means the complication of mesh generation is avoided for the problems with complex geometries. A Stencil Ada...
متن کاملSimulation of turbulent flow around cylinders
Statistical flow modelling does not provide enough detail for many flows of engineering relevance in which unsteadiness is a central feature. This applies particularly to bluff-bodies and assemblies comprising bluff components for which the resolution of peak forces, unsteady loading, acoustics and fatigue are of interest as part of the design process. An example application which has been stud...
متن کامل3D Numerical Study on Scouring Around Bridge Piers Under Unsteady Flow Condition
Local scouring around the bridges piers has always been considered as a problem, especially in rivers. If we do not take the necessary actions to avoid the occurrence of this phenomenon or to reduce its influence, then the bridge's piers will be destroyed. Placing the bridge piers' foundation far from the earth's surface will turn out in a plan which is not economic at all. Experimental studies...
