摘要
For the possible drag reduction application of superhydrophobic surface, the drag characteristics of vehicle models with superhydrophobic surface is studied by water tunnel experiment. The drag characteristic curves and excess 20% experimental drag reduction effect are acquired. The surface energy specialty and slip specialty of superhydrophobic surface are analyzed. The results indicate that the hydrophobic fragments and microstructure bring about low surface energy effect and wall slip effect respectively, which are efficient reasons that superhydrophobic surface possesses drag reduction effect.
