Abstract

It is one of the important issues to represent wettability that decides a liquid shape on a solid surface. There are some previous methods related to wettability using FEM (Finite Element Method), FVM (Finite Volume Method), and particle method. In these methods, particle method has a merit of robustness for topological change such as a droplet that comes out of a tube and reaches on a surface after being broken by gravity. In particle method, a liquid shape is decided by specifying the contact angle between the liquid and the solid, and by modifying the angle using CSF (Continuum Surface Tension) model or potential model. However, these methods have to specify the contact angle in advance, and the angle is not decided with the physical properties of the liquid and the solid. Therefore, this paper proposes a method to represent wettability not by specifying the contact angle, but by calculating the interfacial tension with the surface free energy between the liquid and the solid. As the result of the simulations with some liquid and solid, we have confirmed that wettability can be represented without specifying the contact angles.
