Abstract
The current paper aims at performing large eddy simulation in spectral element framework of a 3 3 wind turbine array in atmospheric boundary layer (ABL) with near wall modelling for rough-wall geometry at very high Reynolds number. The wind turbine rotors have been represented by state of the art reduced order Actuator Line (AL) model analogous to immersed boundary methodology which is computationally more ecient than resolving turbine blade boundary layer. The inow condition is fed from an ABL simulation using spectral interpolation method. We present an analysis of multiscale turbulent dynamics and power generated by a 3 3 wind turbine array from the statistical moments and validate the result from experimental observations.
