In this talk, we introduce a 3D compressible Euler system with additional damping terms. We establish well-posedness of the system for the initial data close to equilibrium. Interesting long-time decay rates are also presented..

摘要:  In this topic, we introduce some results of three-dimensional compressible viscoelastic flows modelled by the Navier-Stokes equations with a density-dependent pressure coupled with the upper-convected Maxwell model in its deformation gradient formulation.
