All the correlations involved in the equation for the rate of dissipation of kinetic turbulence energy are modeled. Approximations derived earlier are used as model relations. Modeling is performed by direct comparison of the approximations with the correlations obtained as a result of a numerical solution of the Navier—Stokes unsteady-state equations. The form of the approximations and the empirical coefficients are determined. Approximations for correlations involved in the equation for the tensor dissipation function are obtained. A new equation for the rate of turbulence-energy dissipation is proposed. The results of the work can be used to determine the Reynolds stresses in second-order turbulence models.
