報告摘要:

   In this talk, we focus on the gas-liquid phase transition  represented by a diffuse interface model. This model  is composed of  the compressible Navier-Stokes system and a modified Allen-Cahn equation. The generalized Navier boundary condition  and the relaxation boundary condition are established in order to solve the problem of moving contact lines on the solid boundary by using the principle of minimum energy dissipation. The local existence and uniqueness of strong solution in three dimensional bounded domain for this type of boundary value problem is proved. Moreover, the sharp interface limit is derived.  The proofs are given by the elementary energy method, the maximum principle and   the method of  matched asymptotic expansion.
