A new airfoil for the supporting struts of smaller-capacity straight-Bladed VAWT

The primary sources of drag for a straight-bladed vertical axis wind turbine (SB-VAWT) are the blades which are also responsible for generating lift. The supporting struts of a SB-VAWT are also responsible for generating additional parasitic drag which reduces the overall power output. It is one of...
