报告摘要:We investigate the Cauchy problem for a generic compressible two-fluid model with equal pressure functions in three dimensions. Global well-posedness of the 3D compressible two fluid model with common pressure has been a challenging problem due to the fact that the system is partially dissipative and its nonlinear structure is very terrible. By exploiting the dissipation structure of the model and making full use of several key observations, we establish global existence and large time behavior of classical solutions to the 3D compressible two-fluid model with common pressure. One of key observations here is that to closure thehigher-order energy estimates of non-dissipative variables, we will introduce the linear combination of two velocities and explore its good regularity, which is particularly better than ones of two velocities themselves.
