Efforts have been made to study the effect of the magnetic fluid lubricant and the sealing of the boundary for the squeeze film between two circular disks when the upper disk having a porous facing with its boundary sealed, approaches the non-porous lower disk normally. The modified Reynolds equations for the fluid region and the governing Laplacian equation for the pressure in a porous region are solved with appropriate boundary conditions. Expressions are obtained for pressure, load carrying capacity and the response time. The results are presented graphically. The combined effect of the magnetic fluid lubricant and sealing of the boundary increases the load carrying capacity significantly and hence the performance of the bearing can be enhanced considerably by sealing the boundary and taking a magnetic fluid as lubricant.
