Some properties of a LaGrangian Wiener-Hermite expansion
Abstract
The turbulent velocity expanded in Hermite functionals of a Gaussian white noise random function advected by the fluid was proposed. The mechanics of converting this proposition into a comutable model is described. The range of validity as an approximation for incompressible, homogeneous, and isotropic turbulence was examined.
