The chapter deals with the problem of the motion of a rigid body in a domain filled by the compressible fluid. We consider the nonhomogeneous boundary condition of the velocity and inflow boundary condition for the density. We study the weak-strong uniqueness property for such problem. The novelty lies in the fact we are considering the general inflow-outflow boundary data which were not considered before in the context of fluid-structure interaction of weak-strong uniqueness.

摘要

The chapter deals with the problem of the motion of a rigid body in a domain filled by the compressible fluid. We consider the nonhomogeneous boundary condition of the velocity and inflow boundary condition for the density. We study the weak-strong uniqueness property for such problem. The novelty lies in the fact we are considering the general inflow-outflow boundary data which were not considered before in the context of fluid-structure interaction of weak-strong uniqueness.
