The restricted nonlinear large eddy simulation approach to reduced-order wind farm modeling
A new approach to the reduced-order modeling of wind farms based on the recently formulated restricted nonlinear large eddy simulation (RNL-LES) framework is introduced. The approach has been shown to accurately reproduce mean flow distributions and turbulence statistics in wall-bounded flows at a fraction of the cost of traditional LES, making it a potentially attractive reduced-order model for studying wind farm behavior over a range of conditions. An appropriately altered version of the actuator disk turbine model is used to evaluate the ability of the RNL-LES framework to simulate very large wind farms in the fully developed regime through comparisons with the standard LES of wind farms under a variety of conditions. Then, the low computational cost of the RNL-LES approach is exploited to conduct a parametric study of several vertically staggered wind farm configurations.
