METHOD OF DIFFERENTIAL CONSTRAINTS: LOCAL EQUILIBRIUM APPROXIMATION IN A PLANAR MOMENTUMLESS TURBULENT WAKE

It is revealed that the local equilibrium approximation (algebraic parametrization of triple correlations of turbulent fluctuations of a vertical velocity component) in the problem of a planar momentumless turbulent wake is a differential constraint for a third-order closure model. The results of nu...

Description
Summary:It is revealed that the local equilibrium approximation (algebraic parametrization of triple correlations of turbulent fluctuations of a vertical velocity component) in the problem of a planar momentumless turbulent wake is a differential constraint for a third-order closure model. The results of numerical experiments that confirm the feasibility of the used known algebraic parametrization of this third-order correlation moment are presented.
