In the present work, the behavior of a flexible disk rotating close to a fixed, a co-rotating, and a counter rotating flat-stabilizers in open air is investigated both experimentally and numerically. The Navier-Stokes equations along with the continuity equation representing the flow in the air-film are discretized using the finite volume method and solved numerically with the SIMPLE algorithm. An experimental test-rig is designed to investigate the effects of the rotation speed, the initial gap height and the inlet-hole size on the flexible disk displacement and its vibration amplitude. Finally, a comparison between the experimental and the numerical results is made.
