Blockage effects in wind farms
Wind Energy, 2020 An experimental study of wind farm blockage has been performed to quantify the velocity decrease that the first row of a wind farm experiences due to the presence of the other turbines downstream.

Modelling the aerodynamics of vertical-axis wind turbines in unsteady wind conditions
, 2013 Most numerical and experimental studies of the performance of vertical-axis wind turbines have been conducted with the rotors in steady, and thus somewhat artificial, wind conditions - with the result that turbine aerodynamics, under varying wind ...

Performance and Economic Analysis of Multi-Rotor Wind Turbine
Emitter: International Journal of Engineering Technology, 2018 Power production of a wind turbine is dependent upon its rotor size and at present wind turbines with large rotor diameter (>175 m) are available in the market. However major problems associated with such large size conventional turbines are their cost &
