Abstract: 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 plane 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.
Keywords: method of differential constraints, semi-empirical turbulence models, algebraic representation of the third-order moment, numerical simulation.
