We present numerical results for aerodynamic vibrations of two circular cylinders in side-by-side arrangement, which are located in a uniform flow. The two closed circular cylinders in numerical computations are arranged in various spacing between the cylinders. It is well known from experimental data that the characteristics of fluid forces acting on the circular cylinders vary depending on the spacing between the cylinders. The computed results at the Reynolds number 1000 are quantitatively compared with the experimental results, and the features of vibrations of two closed cylinders are shown under the biased gap flow.
