An investigation into the use of vortex generators on the blade of vertical axis current turbine in correlation with delaying stall and increasing energy efficiency

The common phenomena in vertical-axis turbines arise from the continuously changing angle of attack (AoA), which results in; flow separation, dynamic stall, unsteady hydrodynamics, complex wake and vortex structures, and Cyclic structural loading. Devices such as vortex generators (VGs) are used to mitigate flow separa...
