Abstract
The experiments are run in an inhomogeneous turbulent shearless layer generated in a wind tunnel with two different meshes. A PIV system synchronized simultaneously with a Mie scattering diffusion concentration system is used in order to obtain the velocity and concentration fields at the same instant. We present here some statistical results for both velocity and concentration and also the mean flux. Filtering and subgrid scale modeling are applied to experimental velocity and concentration field in order to check the effect of the length of filter and the accuracy of subgrid model of LES.
