We present two-dimensinal numerical results of flow around two circular cyrinders in tandem arrangement and show features aerodynamic vibration of the circular cylinders at a certain spacing between two circular cylinders. Two circular cylinders are located in a uniform flow and are supported elastically by two degrees of freedom. In this computation, the finite element approximation is applied to the Navier-Stokes equations, and the Euler implicit scheme is used for numerical time integration. The Reynolds number is set as 1000.
