Numerical Study on Size Effects in the Wettability of Textured Surfaces

[摘要] Super hydrophobic surfaces have attracted a great deal of attention due to their excellent water resistance performents. In this study, Ansys Fluent software is employed to simulate the droplet on the micro-textured surfaces with different structural parameters to explore the effect of the micro-textured structure parameters on the surface hydrophobic properties. The simulation results show that the hydrophobic properties of the surface of the material with the micro-texture are significantly improved and fully accord with the characteristics of the Cassie wetting model. It is also found that the relatively small micro-texture size and the larger micro-texture density are more favorable to obtain surface super hydrophobic properties.
