【摘要】 In this talk, We mainly present the large-time behavior of solutions to an out-flow problem in one-dimensional half space for the Navier-Stokes-Korteweg equations which models compressible fluids with internal capillarity. Applying the center manifold theory, we prove the existence of the stationary solution under a smallness condition on the boundary data and a proper relation between the capillary coefficient κ and Mach number M+ at far field. Then making use of the energy method and the inequality of Poincar´e type, we show that the stationary solution is asymptotically stable under smallness assumptions on the boundary data and the initial perturbation in Sobolev space. This is a joint work with Peicheng Zhu.
