摘要：

In this paper the prediction of friction drag reduction & cavitation inhibition were investigated by water tunnel experiment. The drag characteristic curve and up to 12% drag reduction was acquired experimentally. And the characteristics of cavity were also analysized. The results indicate that the hydrophobic material presents low surface energy effect and wall slip effect respectively, which are efficient reasons for coating surface effect of drag reduction and cavitation.
