| Abstract Scope |
Wetting property which results in the wetting states such as Wenzel or Cassie-Baxter states is one of key factor of surface engineering. The contact state is determined by capillarity reaction between fluids and surfaces, induced by the balance of interfacial tensions of the coinciding interfaces, as well as roughness of the surfaces with morphology in capillarity length scale, which hinders theoretical analysis of wetting phenomena due to its complexity. In this study, we propose a computational model to analyze wetting phenomena on rough surfaces using phase-field approach which is an interfacial tracking method capable of dealing with capillarity reactions on virtually arbitrary shaped surfaces interacting with viscous fluids. It was revealed that the model is capable of rendering both Wenzel and Cassie-Baxter contact states. |
