Abstract

We consider a mathematical model of a rigid body immersed in a viscous, compressible fluid moving with a velocity prescribed on the boundary of a large channel containing the body. We show continuity of the drag functional as well as domain shape stability of solutions in the incompressible limit, with the Mach number approaching zero.
