Abstract

The aim of this paper is to study the local in time well posedness of the incompressible k-ε model in a 3d periodic domain. In the case when turbulent diffusion is much smaller than dissipation, asymptotic expansions are also derived, supposing that the velocity of the fluid can be neglected.
