Abstract
In this investigation, we studied the wake interactions incurred by two nearby spheres at Re=300. We considered all possible arrangements of the two spheres in terms of the distance between the spheres and, the angle inclined with respect to the flow direction. It turns out that significant changes in shedding characteristics are noticed depending on how the two spheres are positioned. In this study, not only quantitative changes in the key physical parameters such as force coefficients and shedding frequencies, but also qualitative changes in shedding patterns are analyzed and reported.
