Wind turbine wake aerodynamics
TLDR
In this article, the aerodynamic properties of wind turbine wakes are studied, focusing on the physics of power extraction by wind turbines, and the main interest is to study how the far wake decays downstream in order to estimate the effect produced in downstream turbines.About:

Large eddy simulation study of fully developed wind-turbine array boundary layers
TL;DR: In this paper, a suite of large eddy simulations (LES), in which wind turbines are modeled using the classical "drag disk" concept, is performed for various wind-turbine arrangements, turbine loading factors, and surface roughness values.
Journal ArticleDOI
A new analytical model for wind-turbine wakes
TL;DR: In this paper, a new analytical wake model is proposed and validated to predict the wind velocity distribution downwind of a wind turbine by applying conservation of mass and momentum and assuming a Gaussian distribution for the velocity deficit in wake.

Large-Eddy Simulation of Wind-Turbine Wakes: Evaluation of Turbine Parametrisations
Yu Ting Wu,Fernando Porté-Agel +1 more
TL;DR: In this paper, a tuning-free Lagrangian scale-dependent dynamic subgrid-scale (SGS) model is used for the parametrisation of the SGS stresses, and the turbine-induced forces (e.g., thrust, lift and drag) are parametrised using two models: (a) the standard actuator-disk model (ADM-NR), which calculates only the thrust force and distributes it uniformly over the rotor area; and (b) the actuatordisk model with rotation, which uses the blade-element theory to

Boundary layer theory
TL;DR: The flow laws of the actual flows at high Reynolds numbers differ considerably from those of the laminar flows treated in the preceding part, denoted as turbulence as discussed by the authors, and the actual flow is very different from that of the Poiseuille flow.

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.

Thin-layer approximation and algebraic model for separated turbulent flows
B. Baldwin,H. Lomax +1 more
TL;DR: In this article, an algebraic turbulence model for two-and three-dimensional separated flows is specified that avoids the necessity for finding the edge of the boundary layer, and compared with experiment for an incident shock on a flat plate, separated flow over a compression corner, and transonic flow over an airfoil.
