Wind farms as sensor arrays of turbulent boundary layer spatio-temporal flow structure
Manuel Ayala, Dennice Gayme, Charles Meneveau
Temporal fluctuations of wind farm-generated power arise from the interaction between atmospheric turbulence, turbine properties, and wind-farm layout. However, accurately characte…
Actuator Disk Models reproduce Actuator Line Model power and thrust fluctuation statistics in wind farm simulations
Manuel Ayala, Dennice Gayme, Charles Meneveau
Actuator-disk models (ADM) are widely used in wind-farm simulations, but their accuracy in reproducing power and thrust temporal fluctuation statistics has not yet been compared to…
Surface Wave-Aerodynamic Roughness Length Model for Air-Sea Interactions
Manuel Ayala, Dennice Gayme, Charles Meneveau
A new model to evaluate the equivalent hydrodynamic length or surface roughness, z0, of ocean waves is developed and tested. The proposed Surface Wave-Aerodynamic Roughness Length…
A Moving Surface Drag Model for LES of Wind over Waves
Manuel Ayala, Zein Sadek, OndÅej FerÄák +3
Numerical prediction of the interactions between wind and ocean waves is essential for climate modeling and a wide range of offshore operations. Large Eddy Simulation (LES) of the…
