A Study on Large Eddy Simulation of High Reynolds Number Flow Past A Square Cylinder

Flow past a square cylinder has been studied extensively for over a century, because of its interesting flow features and practical applications. This problem is of fundamental interest as well as important in many engineering applications. The characteristics of flow around a square cylinder placed at symmetric condition are governed by the Reynolds number (Re). In the present study two dimensional simulations of flow past a square cylinder have been carried out for a Reynolds number of 21400. It has been studied numerically using the large-eddy simulation technique. The modeling of the problem is done by ANSYS 17.1 preprocessing software.
