Abstract:
In this work, we study the numerical solution of the equations
of correlations -or moment of order two - associated with the
Navier-Stokes equations. We treat the spectral transformations of these
equations by admitting directions of homogeneities; the problem of finding
suitable initial conditions within the framework of the numerical resolution
and the writing in two points is dealt with. We provide a new method of
construction of these initial conditions in an intermediate space between
physical space and spectral space (quasi spectral space). This original method
departs from the formalism known in the homogeneous case and takes into
account the presence of the walls. It is all the more interesting as the
experimental data never give enough point of calculation making it possible to
obtain these quantities in a quasi spectral space.
