微肋薄膜减阻的实验研究

EXPERIMENTAL INVESTIGATION OF RIBLETS DRAG REDUCTION FILM

作者根据湍流附面层结构新的解释及非光滑特殊造型表面可以减小流体阻力的事实 ,作者研制了微肋条减阻薄膜 ,贴在赛船上参加比赛 ,获得好成绩[1、2 ] 。作者在风洞中做了贴及不贴微肋薄膜平板试验对比。结果贴微肋薄膜可减阻约 7%。

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%.
