A three-dimensional dynamic mode decomposition analysis of wind farm flow aerodynamics
Xuan Dai, Da Xu, Mengqi Zhang +1
High-fidelity large-eddy simulations are suitable to obtain insight into the complex flow dynamics in extended wind farms. In order to better understand these flow dynamics, we use…
Evaluating the accuracy of the actuator line model against blade element momentum theory in uniform inflow
Luoqin Liu, Lucas Franceschini, Daniel F. Oliveira +3
We evaluate the accuracy of the actuator line model (ALM) approach by performing simulations for the NREL~5~MW wind turbine in uniform inflow using three large eddy simulation code…
Enhanced wind-farm performance using windbreaks
Luoqin Liu, Richard J. A. M. Stevens
The flow speed-up generated by windbreaks can be used to increase the power production of wind turbines. However, due to the increased drag imposed by the windbreaks, their use in…
Diffusion-free scaling in rotating spherical Rayleigh-Bénard convection
Guiquan Wang, Luca Santelli, Detlef Lohse +2
Direct numerical simulations are employed to reveal three distinctly different flow regions in rotating spherical Rayleigh-Bénard convection. In the low-latitude region $\mathrm{I}…
Effect of low-level jet height on wind farm performance
Srinidhi N. Gadde, Richard J. A. M. Stevens
Low-level jets (LLJs) are the wind maxima in the lowest 50 to 1000 m of atmospheric boundary layers. Due to their significant influence on the power production of wind farms it is…
The effect of Prandtl number on turbulent sheared thermal convection
Alexander Blass, Pier Tabak, Roberto Verzicco +2
In turbulent wall sheared thermal convection, there are three different flow regimes, depending on the relative relevance of thermal forcing and wall shear. In this paper we report…
