Scalar dispersion by large eddy simulations and a Lagrangian stochastic subgrid model

Using the additional assumption that the surface reflexion randomizes the phase of the reflected wave, we are able to derive simple expressions for the scattering mean free path of

When running FLEXPART forward in time for a deposit- ing species with a given emission flux (kilograms per re- lease as specified in file RELEASES), the accumulated wet and

It was used to compute a periodic turbulent channel flow case with both the dynamic Smagorinsky model and the present static σ-model.. Note that contrary to the imple- mentation used

the third order moment for the mixed Eulerian scaling exponent is analogous to the second order moment for the Lagrangian passive scalar: in case of intermittency ξ θ (q) is

The anisotropic effect on turbulent kinetic energy transfer is either revealed explicitly in homogeneous shear turbulence or included implicitly in homogeneous rotating flow by the use

In Section 1 we put an emphasis on the Lagrangian model and give a detailed and simple proof of existence of optimal irrigation plans without resorting to parameterizations as done

Variance of scalar, scalar viscous term, scalar production term, scalar advection term, Lagrangian time rate of change, and Eulerian time rate of change, for five values of the

The dynamic procedure is expected improve the functional performance of the model, with a better evaluation of the mean SGS scalar dissipation, and the structural performance, with
