Low-Reynolds-number investigations on the ability of the strip of e-TellTale sensor to detect the flow features over wind turbine blade section: flow stall and reattachment dynamics

چکیده
Abstract. Monitoring the flow features over wind turbine blades is a challenging task that has become more and crucial. This paper devoted to demonstrate ability of e-TellTale sensor detect stall–reattachment dynamics blades. made strip with strain gauge at its base. The velocity field was acquired using time-resolved particle image velocimetry (TR-PIV) measurements an oscillating 2D blade section equipped sensor. PIV images were post-processed movements strip, which compared flow. Results show good agreement between measured regarding dynamics.
