Abstract

In this paper we reformulate a homogenization of Navier-Stokes equations in generalized form and then according to Kolmogorov's scaling theory make an analysis to get a novel closure for fully developed turbulence. Our research in physics is essentially different from those available in the literature, although in some mathematical method it follows Chacon at al (1994). We also explore a novel method to calculate the closure terms in homogenized quations for fully developed turbulence.
