Abstract
Inspired by wind dispersing seeds, this paper presents the performance study of a small-prototype horizontal axis wind turbine (HAWT) by means of low-speed wind tunnel testing. The rotor blade design was based on the Q. Multiflora seed from the Brazilian’s Cerrado vegetation. To evaluate and compare the power coefficient, cp, a baseline conventional rotor blade was built entirely based on Blade Element Momentum (BEM) theory. Both small HAWT have been tested for low wind speeds commonly found in countryside of Brazil, such as 4 up to 6 m/s. An experimental workbench was designed and built to properly measure the rotational speed, output power and torque for the prototype tested. The choice of wind dispersing seed, such as Q. Multiflora has shown potential for future insights on designing’s inspired by nature.
