报告摘要:We investigate vanishing capillarity limit problem of a generic compressible two-fluid model with common pressure.By exploiting the intrinsic dissipation structure of the model and employing several key observations, we show that the unique smooth solution of the generic compressible two--fluid model exists for all time, and converges globally in time to the unique smooth solution of the compressible two-fluid Navier-Stokes equations, as the capillary coefficient tends to zero. Moreover, as a by-product, we also obtain the convergence rate estimates with respect to the capillary coefficient for any given positive time.
