Aerodynamic analysis of large wind farms using two-scale coupled modelling approaches.

Ma, Lun (2021-08)

The effects of turbine aerodynamics and response characteristics of the atmospheric boundary layer on the overall wind farm efficiency are investigated in this research. Various wind farm modelling strategies, which include ...
Blade-resolved CFD simulations of a periodic array of NREL 5 MW rotors with and without towers

Ma, Lun; Delafin, Pierre-Luc; Tsoutsanis, Panagiotis; Antoniadis, Antonis F.; Nishino, Takafumi (MDPI, 2022-01-14)

A fully resolved (FR) NREL 5 MW turbine model is employed in two unsteady Reynolds-averaged Navier–Stokes (URANS) simulations (one with and one without the turbine tower) of a periodic atmospheric boundary layer (ABL) to ...
Preliminary estimate of the impact of support structures on the aerodynamic performance of very large wind farms

Ma, Lun; Nishino, Takafumi (IOP, 2018-06-19)

An extended theoretical model, which is based on a two-scale coupled momentum conservation argument, is proposed to estimate aerodynamic effects of support structures on the performance of ideal very large wind farms. A ...
