TLDR
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.About:

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.
Characteristics of turbulence in a boundary layer with zero pressure gradient
TL;DR: In this article, the results of an experimental investigation of a turbulent boundary layer with zero pressure gradient are presented and the importance of the region near the wall and the inadequacy of the concept of local isotropy are demonstrated.
Neutrally stratified boundary-layer flow over roughness changes and topography
TL;DR: In this paper, a linear model for neutral surface-layer flow over complex terrain is presented, which makes it possible to make high-resolution computations for an arbitrary distribution of surface roughness and topography.

A mixed spectral finite-difference model for neutrally stratified boundary-layer flow over roughness changes and topography
TL;DR: In this paper, a linear model for neutral surface-layer flow over complex terrain is presented, which combines the simplicity and computational efficiency of linear methods with flexibility for closure schemes of finite-difference methods.

Simulation of Effect of Wind Barriers on Airflow
TL;DR: In this article, the authors developed a quantitative, theoretical simulation of airflow normal to narrow wind barriers of various porosities and, when possible, verify the results using experimental data, using finite difference methods having a combination of upwind and central difference schemes.
