Aero-acoustics noise evaluation of H-rotor Darrieus wind turbines

Mohamed, M.H. - In: Energy 65 (2014) C, pp. 596-604

The problems aided with wind turbine noise have been one of the more studied environmental influence areas in wind energy engineering. Noise levels can be measured, but, similar to other environmental attentions, the public's perception of the noise impact of wind turbines is in part a...

Computational analysis of shrouded wind turbine configurations using a 3-dimensional RANS solver

Aranake, Aniket C.; Lakshminarayan, Vinod K.; … - In: Renewable Energy 75 (2015) C, pp. 818-832

The use of a shroud is known to improve performance. In this work, the flow physics and performance of shrouded turbines is assessed by solving the Reynolds Averaged Navier–Stokes equations supplemented with a transition model. Shroud geometries are evaluated for their augmentation of mass...
