Abstract

This paper presents a numerical simulation of two dimensional unsteady flow past a square cylinder at an angle to the incoming flow. The main objective of this study were to capture the features of flow past a square cylinder in a domain with the use of CFD for the Reynolds number (Re) considered in the range 50-200 so that flow is laminar. The shape and size of the recirculation bubble downstream of the cylinder are strong function of orientation. Results are presented in terms of Strouhal number (st), Time-averaged velocity and Vorticity field. The Lift Coefficient (cl) and velocity component in the wake region were monitored for calculation of Strouhal number. The variation of Strouhal number with Reynolds number was found from the analysis.
