报告摘要:In this talk, we are concerned with the incompressible limit of Navier-Stokes equations. First, we review some results on the incompressible limit or low Mach number limit of Navier-Stokes equations. Then we study the incompressible limit of all-time strong solutions to isentropic compressible Navier-Stokes equations with ill-prepared initial data and vorticity-slip boundary conditions in three-dimensional bounded domains. We derive the uniform estimates with respect to the Mach number and all time by establishing a nonlinear integral inequality with decay property. Then as the Mach number tends to zero, the convergence to global strong solution of incompressible Navier-Stokes equations is shown. This talk is based on the joint work with Dr. Lu Yang (IAPCM).
