摘要: Abstract We prove the existence of a weak solution to equations describing inertial motions coupled system constituted by rigid body containing viscous compressible fluid. then provide weak-strong uniqueness result that allows us completely characterize, under certain physical assumptions, asymptotic behavior in time corresponding smooth data restricted “size”, and show it tends uniquely determined steady-state.
