SINOPSIS

Efforts have been made to study and analyze the performance of a magnetic fluid based squeeze film between porous circular plates with porous matrix of variable film thickness. The associated Reynolds equation is solved with appropriate boundary conditions and the expressions for pressure, load carrying capacity and response time are obtained. The results are presented graphically as well as in tabular form. It is observed that these performance characteristics increase with the increasing magnetization parameter thereby, indicating that the performance of the bearing with magnetic fluid lubricant is better than that with the conventional lubricant. Moreover, there is a very significant observation that for a proper selection of the thickness ratio parameter, a magnetic fluid based squeeze film bearing with variable porous matrix thickness can be made to perform considerably better than that of a conventional porous bearing with a uniform porous matrix thickness working with a conventional lubricant.
