Abstract
On the basis of the Brinkman model (BM), the main objective of this paper is to predict the viscous shear effects on the squeeze-film characteristics between porous circular disks. According to the results obtained, the influences of viscous shear stresses on the squeeze-film behavior are significant and not negligible. It is found that the BM predicts quite different squeeze-film action to those derived by using the Slip-flow model (SFM) and Darcy model (DM). When comparing with that of the SFM, the viscous shear effects of the BM provide an enhancement in the load-carrying capacity and, then, increase the response time of the squeeze-film behavior; but these trends are reversed as compared to that derived by using the DM.
