The performance of vertical-axis wind turbines (VAWTs) are substantially affected by the
phenomenon of dynamic stall which is induced by the variations of angle of attack of rotating …

The flow performance of vertical-axis wind turbines (VAWTs) is significantly deteriorated by
dynamic stall at low tip-speed-ratios (TSR). Dynamic stall occurs periodically during the …

To fulfill the increasing need for large power generation by wind turbines, the concept of
multirotor wind turbines has recently received attention as a promising alternative to …
