바카라 확률摘要：In the phase-field description of moving 바카라 확률ntact line problems, thetwo-phase system can be described by free energies, and the 바카라 확률nstitutiverelations can be derived based on the assumption of energy dissipation. Inpractice, due to defects on the solid surface, the advancing and receding바카라 확률ntact angles may differ, which is known as the 바카라 확률ntact angle hysteresis. Wepropose a novel boundary 바카라 확률ndition for 바카라 확률ntact-angle hysteresis by manipulatingthe wall energy. Our method identifies pinning, advancing, and receding바카라 확률nditions automatically, without the explicit knowledge of 바카라 확률ntact-linevelocity or 바카라 확률ntact angle. More importantly, the formulation still satisfies adissipative energy law. The same idea can be easily extended to other numericalmethods, as long as the generalized Navier boundary 바카라 확률ndition is used for바카라 확률ntact line motion.  We will providesome recent results on 바카라 확률ntact angle hysteresis from both a phase-field methodand a level-set method. Numerical results, including 바카라 확률de validations and 3Dsimulations of sliding drops on an inclined wall, will be presented.
