Ferro Fluid Based Squeeze Film in a Longitudinally Rough Surface Bearing of Infinite Width: A Comparative Study

A hydromagnetic squeeze film in a longitudinally rough parallel surface bearing has been discussed with the consideration of two different form of the magnitude of the associated magnetic field. In the light of the model of Christensen-Tonder regarding surface roughness, the load capacity is obtained after getting the pressure distribution by solving the stochastically averaged Reynolds' equation. The results presented here indicate that the magnetization offers a good amount of help in decreasing the unfavorable effect of roughness. In the case of the trigonometric form of magnitude it helps most. Besides, providing an additional degree of freedom, this article suggests some scopes for reducing the adverse effect of variance positive, skewness positive by magnetization and standard deviation in the case of negatively skewed roughness when negative variance is involved. Comparison of performance for both the forms of the magnitude informs that the trigonometric form of the magnitude presents a better picture to be used in the industry.
