✦ Synopsis

We propose a scheme to reconstruct the flow field up to second order in a cell composed of four lattices nodes in 2 dimensions. The information contained in the higher order moments of the distribution functions is used to construct an interpolation scheme of second order for the velocity field.

A direct numerical simulation of a turbulent flow field with a lattice BGK method is presented. A spatial coarse graining of the numerical results is compared with the expected LBGK dynamics for a flow field on a reduced lattice size. This comparison permits to exhibit subgrid properties of the flui
