Abstract

This paper presents the results of flow over square cylinder with dissimilar leading edges such as corner recession and corner arc at a Reynolds number 200. The leading edges are modified in such a way that the dimensions of the bottom leading edge are kept fixed and that of top leading edge is varied in the predefined proportions or cut ratios between 0 and 1 with respect to bottom edge. This study reveals that the flow over square cylinder with dissimilar leading edges shows an inverse relationship between Strouhal number and coefficient of drag for cut ratios less than 0.5 but beyond 0.5, both these parameters register an increasing trend.
