Modeling of the return of turbulence to an isotropic state

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-dep...

description 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.[PUBLICATION ABSTRACT]
