Magnetic fluid based squeeze film between porous circular disks with sealed boundary

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 d isks when the upper disk having a porous facing with its boundary sealed, a pproaches the non-porous lower disk normally. The modified Reynolds equatio ns for the fluid region and the governing Laplacian equation for the pressu re in porous region are solved with appropriate boundary conditions. Expres sions are obtained for pressure, load carrying capacity and the response ti me. The results are presented graphically. The combined effect of the magne tic fluid lubricant and sealing of the boundary increases the load carrying capacity significantly and hence the performance of the bearing can be enh anced considerably by sealing the boundary and taking a magnetic fluid as l ubricant.
