In this paper, the squeeze film characteristics between two circular parallel plates containing a single central air bubble with sinusoidal relative motion are investigated theoretically based on the nonlinearized theory considering the combined effects of air bubble and fluid film inertia, which was derived in the previous paper. The nonlinear ordinary differential equation with respect to the radius of the air bubble is solved by the Runge-Kutta-Gill method, and then the air bubble pressure and fluid film pressure are determined. The numerical results are compared with the analytical results based on the perturbation method. From the numerical results, the combined effects of the single central air bubble and fluid film inertia on squeeze film characteristics, such as the radius of the air bubble, air bubble pressure and fluid film reaction force, are clarified.
