We investigate the incompressible flow past a square cylinder immersed in wake of an upstream nearby splitter plate separating two streams different velocity. The bottom stream Reynolds number, based on side, $Re_B=56$ is kept constant while top-to-bottom numbers ratio $R\equiv Re_T/Re_B$ increased range $R\in[1,6.5]$, corresponding to coupled variation bulk number $Re\equiv(Re_T+Re_B)/2\in[56,...
