摘要

The paper 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. The existence of the weak solutions is shown. 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.
