报告题目: Behaviors of Navier-Stokes(Euler)-Fokker-Planck equations

报告:   李海梁 教授

报告摘要We consider the pointwise space-time behaviors of  global solutions to the initial value problems for the multi-dimensional compressible Navier-Stokes(Euler)-Fokker-Planck equations, which is used to simultate the two phase motion of particle-liquid mixture through the relaxation mechanism. It is shown that due to the micro-macro coupling effects, the sound wave type propagation of  the NSFP or EFP system for two-phase fluids is observed with the wave speed determined by the two-phase fluids. This phenomena can not be obsered for the pure Fokker-Planck equation and the Euler equation with fritional damping.
