A study on the performance of a magnetic fluid based squeeze film in curved porous rotating rough annular plates and deformation effect

Efforts have been made to analyze the behaviour of a magnetic fluid based squeeze film between rotating transversely rough porous annular plates incorporating elastic deformation. The results suggest that the roughness of the bearing surfaces affects the performance adversely although; the bearing registers an improved performance owing to the magnetic fluid lubricant. It is seen that the deformation causes reduced load carrying capacity. This investigation reveals that the negative effect of porosity, deformation and standard deviation can be minimized up to certain extent by the positive effect of the magnetic fluid lubricant in the case of negatively skewed roughness.
