报告摘要:

fluid-particle model is extensively used in many industries such as sprays, aerosols etc. in this paper, we investigate the wave phenomena to a fluid-particle model described by the three-dimensional vlasov-fokker-planck equation coupled with euler equations. first, we prove the time-asymptotically nonlinear stability of the planar rarefaction wave for both 3d e-vfp systems. consequently, a new two-fluid model with one fluid equipped with the isothermal pressure and the degenerate viscosity coefficients depending on the corresponding density function linearly is derived from the chapman-enskog expansion of the vlasov-fokker-planck equation around the local maxwellian.
