The numerical computation of turbulent flows
Brian Launder,D. B. Spalding +1 more
TL;DR: In this paper, the authors present a review of the applicability and applicability of numerical predictions of turbulent flow, and advocate that computational economy, range of applicability, and physical realism are best served by turbulence models in which the magnitudes of two turbulence quantities, the turbulence kinetic energy k and its dissipation rate ϵ, are calculated from transport equations solved simultaneously with those governing the mean flow behaviour.

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.

Appropriate boundary conditions for computational wind engineering models using the k-ϵ turbulence model
Peter Richards,R.P. Hoxey +1 more
TL;DR: In this paper, velocity and turbulence profiles associated with the k-ϵ turbulence model are proposed which produce homogeneous conditions, and the cospectrum for the Reynolds stress exhibits a characteristics frequency n o ≈ u ∗ / z which is consistent with the suggested profile equations.
Journal ArticleDOI
On nonlinear K-l and K-ε models of turbulence
TL;DR: In this paper, a nonlinear K-l and K-e model is proposed to predict the normal Reynolds stresses in turbulent channel flow much more accurately than the linear model, and the nonlinear model is shown to be capable of predicting turbulent secondary flows in non-circular ducts.
