Abstract

Large Eddy Simulations of a constant-density flow carrying a passive scalar around a square cylinder at Reynolds numbers Re = 1000 and Re = 1500 are performed. We describe the three-dimensional topology of the turbulent flow in terms of intense longitudinal counter-rotating coherent vortices. We show also a change of regime concerning spanwise Kelvin–Helmholtz (KH) vortices. At the lower Reynolds number, they roll up downstream of the obstacle to form the von Karman vortex street (VK). At higher Reynolds, they form immediately in the separating shear layer on the two sides of the cylinder. The role of vortices in the passive-scalar mixing is also looked at. To cite this article: C.
