An analysis of the effect of axial current induced pinch on the squeeze-film behavior between two annular disks, when the upper disk which has a porous facing and is parallel to the stationary nonporous disk moves normal to itself approaching the lower disk, is presented. The analytical results for the pressure distribution, load-carrying capacity, and the film thickness as a function of time are obtained and the effect of pinch on these quantities is studied. It is found that a load proportional to the square of the axial current can be sustained even when there is no flow.
