Experimental Investigation on the Performance of Varying Thickness H-Darrieus Rotor

Abstract

Towards developing wind turbines researchers contributed substantially by doing researches on different blade parameters. However, there is still a good scope of improvement of the VAWTs performance by installing asymmetric blades with rotor modification. The present work enlightens the effect of variable thickness blade considering outward blade pitch angle at low wind speed condition. The thicker portion of varying thickness blade is installed on top of the H-Darrieus rotor. This type of rotor configuration is not efficient for mechanical and electric power generation due achieving less power coefficient in low wind speed condition.
