We address a fluid-structure system which consists of the incompressible Navier-Stokes equations and a damped linear wave equation defined on two dynamic domains. The equations are coupled through transmission boundary conditions on the free moving interface separating the two domains. Given sufficiently small initial data, we prove the global in time existence of solutions by establishing a key energy inequality which in addition provides the exponential decay of solutions.
