Abstract

Abstract

Based upon the new explanation of the structure of turbulent boundary layer and the fact that specially designed non-smooth surface can reduce fluid drag,the authors have designed and fabricated the Riblets Drag Reduction Film.This Film was covered on racing boats,the boats and recieved excellend awards in competition.The authors also tested the flat plates with and without the Biblets Drag Reduction Film in wind tunnel and compared their fluid drags.The results showed that the Drag of the covered plate has been reduced by 7%.
