Large-eddy simulations of the Northeastern US coastal marine boundary layer

Journal of Physics: Conference Series

Cheung, Lawrence C.; Kaul, Colleen M.; Laros, James H.; Blaylock, Myra L.; Churchfield, Matthew J.

In this study, large eddy simulations (LES) of offshore boundary layers near the Nantucket coast are performed using Nalu-Wind. The marine boundary layer conditions are chosen to match the predominantly unstable and neutral conditions measured by the Cape Wind platform. The appropriate domain, resolution, and boundary condition settings required for the LES are established through this work. Differences between stable and unstable cases are found in the wind speed profiles, averaged statistics, and wind spectra, and explained in terms of stratification effects.

Overview of FY20 Q2 milestone completion: Actuator Disk Improvements and Hardening PowerPoint]

Sakievich, Philip S.; Knaus, Robert C.; Laros, James H.; Cheung, Lawrence C.; Blaylock, Myra L.; Maniaci, David C.; Martinez-Tossas, Luis; Churchfield, Matthew

Milestone Description: Enhance Nalu-Wind's actuator disc model through hardening, documenting, stress-testing, verifying, and validating. Existing workflows will be improved by reducing the data output stream, and by making the analysis capabilities more modular and generally better. These model capabilities are needed by other A2e areas, namely Wake Dynamics, AWAKEN, and VV&UQ.
