£Ábstract: In this paper, we use Jourdain's
principle to generate the dynamical equations and their dynamical boundary conditions of a
complex mechanical system composed of rigid, tow immiscible fluid and elastic bodies,
perfect and extend Rumyjantsev 's£Û£´,£µ£Ý¡¢Liu's£Û£¶£Ýworks.
Keywords: rigid-fluid-elastic coupled system , compressible
viscous fluid, stress tensor, capillarity force, Jourdain's principle.
