Comparative wind tunnel investigation of sail profiles for windmills
Technical Report
·
OSTI ID:7108651
Low speed wind tunnel tests were carried out to determine sail profiles for improving the performance of classical Dutch windmills. Results are presented in graphs, in which the coefficient of force-in-plane related to the wind velocity is depicted as function of the ratio between circumferential speed and effective wind velocity. It appears that improvements in performance may be obtained by changing the shape of the sails.
