Extended Self Similarity in numerical simulations of 3D anisotropic turbulence

Abstract

Using a code based on the Lattice Boltzmann Equation, we have performed numerical simulations of a turbulent shear flow. We investigate the scaling behaviour of the structure functions in presence of anisotropic homogeneous turbulence, and we show that although Extended Self Similarity does not hold when strong shear effects are present, a more generalized scaling law can still be defined.
