Genesis and Dynamics of very-large-scale Motions in the Atmospheric Boundary Layer and their Interactions with Utility-scale Wind Turbines

Funding Agency: NSF CBET Fluid Dynamics, Program Manager Ronald Joslin

Award Number: 1705837

Project Period: September 1, 2017 – August 31, 2020

Abstract: In wind energy technology, predicting the evolution of wind turbine wakes under different atmospheric conditions is important for optimizing power production from a wind farm and mitigating damaging loads on the turbines due to detrimental wake interactions. This project aims to investigate the origin, evolution and regeneration of what are called very-large-scale motions (VLSMs) that evolve in the layer of air near the blade surface, termed the atmospheric boundary layer (ABL), and their interactions with utility-scale wind turbines. As the scale of wind farms continues to grow and as wind turbines increase in size, VLSMs are expected to profoundly influence wind power production and the downstream evolution of wind turbine wakes. However, the origin and dynamics of VLSMs are not well understood in some cases, and therefore their effects and interactions with utility-scale wind turbines are difficult to predict. This project advances numerical simulations and proof-of-concept laboratory experiments on this topic. Additionally, undergraduate students are being trained to measure wind velocities at the University of Texas Dallas mobile LIDAR (Light Imaging, Detection, And Ranging) station, which is a unique facility for education and outreach activities. This training impact students from a wide range of backgrounds and makes them aware of important topics, such as meteorology, extreme weather phenomena, anthropogenic effects on the environment and renewable energy.

 

Transport of Aerosolized Oil Droplets in Marine Atmospheric Boundary Layer: Coupling Wind LiDAR Measurements and Large-Eddy Simulations

Funding Agency: Gulf of Mexico Research Initiative, Year 8-10 Research Grant (RFP-VI)

Project Period: January 1, 2018 – December 31, 2019

url: http://research.gulfresearchinitiative.org/research-awards/projects/?pid=307

Abstract: The proposed research aims to develop a numerical tool for thorough predictions of production of aerosolized oil droplets at the sea-air interface, their transport within the marine atmospheric boundary layer (ABL) and deposition over a coastal region. The scientific goals of the proposed project are to: 1) understand the role of ABL structure and wave motion on aerosol generation at the sea-air interface; 2) investigate effects of transitioning from the ocean to the coast on aerosol concentration and distribution; 3) develop eddy-diffusivity models for regional meteorology algorithms by avoiding the typical assumption of a flat and homogeneous ocean surface and including a realistic wave motion. This project will be conducted through two interrelated tasks: one LiDAR measurement campaign will be performed in the Galveston area, TX, to generate unprecedented simultaneous and co-located observations of wind speed and aerosol concentration, while high-fidelity wind-wave coupled large eddy simulations (LES) will be performed to investigate aerosol dynamics, and finally reproduce the LiDAR observations.
