Experimental Study of a Shearless Turbulent Mixing Layer Subjected to Solid Body Rotation

The shearless turbulence mixing layer is a simple case of inhomogeneous turbulence where transport effects can be studied independently of other effects. It is formed by two grids put side by side, generating two turbulent flows, having different intensities and length scales. Since there is no mean shear, there is no turbulence production and the spreading of the mixing layer is controled by the intrisic properties of turbulence. Experimentally, this flow was studied by Gilbert [1] and Veeravalli and Warhaft [2].
