Parallel surface squeeze film bearing design system, formed by two parallel surfaces with the upper surface having squeeze velocity and the lower one stationary, is numerically discussed. The modified Reynolds equation is derived using ferrohydrodynamic theory by Shliomis with static locally-dependent (spatially varying) as well as static constant transversely (vertically) strong magnetic fields, and continuity equation. Using this equation, expressions for film-pressure distribution and load-carrying capacity are derived. The results for dimensionless film-pressure distribution (P) and load-carrying capacity (
) are calculated for different parameters and discussed. Some comparisons of these results are also made when conventional lubricant is used. Summary of the results show better performance of the system when ferrofluid lubricant is used.
