The Evaluation of a Rigid Sail of Ship Using Wind Tunnel Test

Abstract:

This paper described the evaluation of rigid sail performances by using the wind tunnel test. The rigid sail models were developed in the three variations of shape geometry which was having the same value of aspect ratio. The tests were performed to investigate the performances of sail models in terms of lift, drag, resultant, driving and heeling coefficient. The three sail models were tested at the variation of angle of attack such as 15^o, 20^o and 25^o respectively, and it was fluided by a uniform flow of air with three different speeds. The comparisons of test results were evaluated to look for which sail models had the best performance. Based on the test results, Model 2 which is a triangle shape had generated a maximal efficiency and thrust force compare to the other models.Keywords: rigid sail, wind tunnel, sailing ship, renewable energy
