Abstract: A successful description of a convective boundary layer requires that the model employed takes into account the nonlocal nature of turbulent convection. In this paper new third-order moments (TOMs) are presented and tested. ...

Abstract: In this work the role played by the transport equations including nonlocal terms in simulating the atmospheric turbulence is investigated. Two different models are compared: the first one is a standard E?ε model solving ...

Abstract: In this paper the results of numerical simulation experiments on the interaction between a neutrally stratified atmospheric flow and a symmetric 3D obstacle are presented and discussed. These experiments provide evidence ...

Abstract: Spray, a 3D Lagrangian particle model for the simulation of complex flow dispersion, is presented. Its performance is tested against the Environmental Protection Agency wind tunnel concentration distribution of passive ...
