• This paper analyzes the vibrational response of square cylinders enclosed in a vessel of liquid and subjected to forced vibrations. Inertia force acting on each cylinder and damping effects are clarified by solving Navier-Stokes equation of motion for fluid under the assumption of viscous flow and using the fluid field network theory, in which the non-steady flow in cylinder-to-cylinder clearance is assumed to be two-dimensional. Comparing and checking the experimental and analytical results from various models of submerged square cylinders arranged symmetrically, we find that both agree well qualitatively and quantitatively.
