The dynamics of high-inertia particles in the logarithmic layer of a wall turbulent flow has been studied using Lagrangian stochastic simulation. Because of the linear dependence of the turbulent time scale on the distance to the wall in the logarith

The numerical stochastic Lagrangian modeling of the passive tracer in a convective atmospheric boundary layer (CABL) was performed based on the random walk and Langevinmodels of turbulent dispersion. The statistical structure of turbulence is modeled
