MODELING OF THE RETURN OF TURBULENCE
TO AN ISOTROPIC STATE

The study models a correlation that involves pressure 
oscillations and that determines the return of turbulence to an isotropic 
state. The modeling is carried out via a direct comparison of approximations 
put forward previously with correlations resulting from a numerical 
calculation of the time-dependent Navier-Stokes equations. The 
form of the approximations and the empirical coefficients are determined. 
The results can be employed for constructing new turbulence models 
of the second order.
