Abstract

Based on the ferrohydrodynamic theory by R. E. Rosensweig and continuity equation, ferrofluid (FF) lubricated different exponential squeeze film-bearing designs are studied. Since uniform magnetic field does not effect on the performance of the bearing design system, variable form of magnetic field is considered to control FF flow behaviour. Expressions for pressure and load-carrying capacity are obtained by the methods of averaged inertia and regular perturbation. Results for dimensionless load-carrying capacity are calculated and compared. Some comparisons are also made with the previous study. Results show the significant contribution of FF on the designed problem.
