Abstract
Dynamic stall of vertical axis wind turbine blades strongly affects the efficiency of vertical axis wind turbines, especially at low tip speed ratios. Here we report measurements using stereoscopic particle image velocimetry of the dynamic stall behaviour of such turbines, and discuss the factors affecting the evolution, strength, and timing of vortex shedding from the turbine blades. It is found that tip speed ratio alone is insufficient to describe the circulation production and vortex shedding behaviour, and a more complete scaling is proposed.
