Anisotropic Wetting and Fluidic Phenomena on Biological Texture and Hydrodynamic Experiments Testing on Different Low Viscous Resistance Surfaces

Sharkskin effect is progressively coming into the picture in recent several decades, especially focusing on its drag reduction effect in turbulence. The up‐to‐date research in this article reveals the anisotropic wetting and fluidic phenomena on different sharkskin surfaces. Firstly, the contact angle model based on anisotropic pattern is established. Secondly, the anisotropic wetting and fluidic properties are investigated, and the experimental results can define the relationship between wetting parameters and stretching ratio, and in addition, the anisotropic model is validated. Finally, the possible hypotheses elucidating the wetting model and experiment results are put forward.
