DESCRIPTION:Sébastien Le Fouest    \nAccording to the International E
 nergy Agency\, the global net-zero emissions objective requires the instal
 led wind power capacity to increase 11-fold between 2020 and 2050. The sci
 entific community has recently voiced concerns about the logistic feasibil
 ity of scenarios expecting wind power to meet this target. Diversifying wi
 nd turbine technology can help mitigate these concerns. Vertical-axis wind
  turbines provide an attractive design that complements their ubiquitous h
 orizontal-axis counterparts. These turbines can operate in a broad range o
 f wind conditions and emit little noise during operation\, making them ide
 al for urban applications. However\, the aerodynamic complexity of vertica
 l-axis wind turbines has hampered their industrial deployment. The blades
  of vertical-axis wind turbines encounter varying flow conditions througho
 ut a single turbine rotation\, even in a steady wind. Varying flow conditi
 ons can give rise to flow separation and dynamic stall. Dynamic stall is c
 haracterised by the formation\, growth\, and shedding of large-scale vorti
 ces. Vortex shedding on the turbine blades leads to a significant loss in 
 efficiency and load fluctuations that jeopardise the turbine's structural 
 integrity. This thesis investigates the occurrence and control of dynamic 
 stall on vertical-axis wind turbines.
