Abstract:

The properties of scalar variables, that allow to distinguish between turbulent and nonturbulent zones of shear flows, are investigated. The dynamics of the probability density function pdf of such a scalar is considered and a numerical solution technique based on stochastic simulation is developed. The second order closure is extended to axisymmetric shear flows and different closures for the turbulent transport of Reynolds stresses are evaluated. Keywords Turbulence Closure Shear flow.
