On the Impact of Wind Farms on a Convective Atmospheric Boundary Layer
With the rapid growth in the number of wind turbines installed worldwide, a demand exists for a clear understanding of how wind farms modify land-atmosphere exchanges. Here, we conduct three-dimensional large-eddy simulations to investigate the impact of w ...
Springer2015Interaction between large wind farms and the atmospheric boundary layer
Fernando Porté Agel, Yu-Ting Wu, Hao Lu
Accurate prediction of atmospheric boundary layer (ABL) flow and its interactions with wind turbines is of great importance for optimizing the design and efficiency of wind farms. This study first focuses on recent efforts to develop and validate a large-e ...
Elsevier2014On the Development of a Dynamic Non-linear Closure for Large-Eddy Simulation of the Atmospheric Boundary Layer
A dynamic procedure is developed to compute the model coefficients in the recently introduced modulated gradient models for both momentum and scalar fluxes. The magnitudes of the subgrid-scale (SGS) stress and the SGS flux are estimated using the local equ ...

2014A modulated gradient model for scalar transport in large-eddy simulation of the atmospheric boundary layer
As a simple alternative to the standard eddy-diffusivity closure, a nonlinear subgrid-scale (SGS) flux model is introduced and implemented in simulations of a neutral atmospheric boundary layer and a stable atmospheric boundary layer. The new model compute ...

2012Large-eddy simulation of atmospheric boundary layer flow through wind turbines and wind farms
Fernando Porté Agel, Yu-Ting Wu, Hao Lu
Accurate prediction of atmospheric boundary layer (ABL) flow and its interactions with wind turbines and wind farms is critical for optimizing the design (turbine siting) of wind energy projects. Large-eddy simulation (LES) can potentially provide the kind ...
Elsevier2011Large-eddy simulation of a very large wind farm in a stable atmospheric boundary layer
When deployed as large arrays, wind turbines significantly interact among themselves and with the atmospheric boundary layer. In this study, we integrate a three-dimensional large-eddy simulation with an actuator line technique to examine the characteristi ...
