DNS and LES of a Shear-Free Mixing Layer
Abstract
The shear-free mixing layer represents one of the simplest inhomogeneous flows. It consists of two distinct' homogeneous regions of different turbulent kinetic energy interacting through a layer of rapid transition. The layer is said to be shear-free since the two homogeneous regions have no relative velocity. While flows encountered in nature or industrial applications are more often not devoid of shear, the study of the shear-free mixing layer is nevertheless useful since it allows the mixing properties of turbulence to be examined in a simplified environment. Indeed, turbulent transport properties in shear flows are more difficult to track since they can be overwhelmed by production sources originating from gradients in the mean velocity.
