Abstract


In this paper, a theoretical analysis of the effects of micropolar on the squeeze film lubrication between parallel stepped plates is presented. The modified Reynolds equation accounting for the viscosity variation in micropolar fluid is mathematically modelled. A closed form expressions are obtained for load carrying capacity and squeeze film time. According to the results obtained, the influence of micropolar enhances the squeeze film pressure, load carrying capacity and decreases the response time as compared to the classical Newtonian lubricant case. The load carrying capacity decreases as the step height increases.
