Statistics of Coherent Fine Scale Structure in Turbulent Mixing Layer,stablish the theory of turbulence which can explain the intermittency in small scales (Townsend, 1951; Tennekes, 1968; Lundgren, 1982; Pullin and Saffman, 19893; Saffman and Pullin, 1994). Most of them are based on an assumption that turbulence is composed of randomly distributed fine scale eddies s

Structure and Dynamics of Small-Scale Turbulence in Stably Stratified Homogeneous Shear Flows,f strain S, and scalar (density) gradient.Conditional sampling of direct numerical simulation (DNS) results is used in the analysis. In homogeneous shear flow without buoyancy, high-amplitude rotation-dominated regions consist of tube-like structures with distinct spatial orientation due to the pres

Spectral Eddy-Viscosity Based Les of Shear and Rotating Flows, with those obtained through a double filtering in spectral space. Afterwards, we present the spectral-dynamic model, which accounts for cutoff spectra not following Kolmogorov’s law, It is applied in particular with success to a a plane channel..For flows in complex geometries, we employ the filter
