Journal ArticleDOI
Renormalization group analysis of turbulence I. Basic theory
Victor Yakhot,Steven A. Orszag +1 more
TL;DR: In this article, a dynamic renormalization group (RNG) method for hydrodynamic turbulence was developed, which uses dynamic scaling and invariance together with iterated perturbation methods, allowing us to evaluate transport coefficients and transport equations for the large scale (slow) modes.
Journal ArticleDOI
Development of turbulence models for shear flows by a double expansion technique
TL;DR: In this article, a two-equation model and Reynolds stress transport model are developed for turbulent shear flows and tested for homogeneous shear flow and flow over a backward facing step.
Journal ArticleDOI
Renormalization-group analysis of turbulence.
Victor Yakhot,Steven A. Orszag +1 more
TL;DR: Using renormalization-group methods and the postulated equivalence between the inertial-range structures of turbulent flows satisfying initial and boundary conditions and of flows driven by a random force, the Kolmogorov constant and Batchelor constant are evaluated and the skewness factor and power-law exponent are evaluated.
Journal ArticleDOI
Extended Boltzmann kinetic equation for turbulent flows.
TL;DR: This paper explains the method for modeling fluid turbulence using an extended kinetic (Boltzmann) equation and shows its effectiveness with the use of a computationally efficient implementation in terms of a discrete or “lattice” Boltzmann equation.
Journal ArticleDOI
The renormalization group, the e-expansion and derivation of turbulence models
Victor Yakhot,Leslie M. Smith +1 more
TL;DR: In this paper, the authors reformulated the renormalization group (RNG) and the expansion for derivation of turbulence models, and showed that including the random-force contribution to ℰ-production results in the cancellation of all the O(R 1/2 ) terms.
