抄録

In order to develop a simulation method that can treat flows containing various multi-components as one fluid system, we propose a model which can represent the relation of interfacial tensions on three phase contact line faithfully. Our model is based on a front-tacking method. By comparing some schemes of interfacial tension representation, we found that three-point finite difference without extrapolation can represent the curvature and static balance of tension among interfaces very accurately. Then we performed a drop spreading on a solid surface by the proposed model and dynamic contact angles were represented.
