Abstract

In this study the research is focused on the numerical simulation and wind tunnel experiment of leading edge protuberances on blades performance at the stall region of small-scale horizontal axis wind turbine with variable rotational speed Taguchi Method has been used to set up the numerical experiments in search of a set of geometric parameters of leading edge protuberances on blades From numerical simulation and wind tunnel experimental results showed that the optimal parameters of the leading edge protuberances on blades has higher C_p and torque than other without the leading edge protuberances rotor models at the lower tip speed ratio From observing the flow fields on the blades it can be seen that the sinusoidal leading edge begin the vortex convergence phenomenon The vortex convergence phenomenon can improve the performance during the stall region for HAWT and this result show out the flow control in the blade is possible
