Webi.e. along a turbine row. In that case the wind-ward turbine (or turbines) is deliberately yawed at a certain angle with the wind direction, i.e. it is misaligned, leading to a decrease in energy yield. Also, as a result a lateral force will be ex-erted on the flow and the wake will be diverted away. Therefore, the leeward turbines will be http://cnki.nbsti.net/kcms/detail/detailall.aspx?filename=1021805608.nh&dbcode=CDFD&dbname=CDFD2024 thor god of thunder read online https://stbernardbankruptcy.com
