Abstract
In this paper the general Reynolds type equation of finite porous partial journal bearing lubricated with micropolar fluid is solved numerically by using finite difference technique. The first order non-linear equation for time height relation is solved numerically with the given initial condition. From the numerical results obtained, it is observed that, the effect of micropolar fluid is to increases the film pressure, the load carrying capacity and to lengthen the squeeze film time as compared with Newtonian case. The reduction in load carrying capacity and the response time of porous partial journal bearings can be compensated by the use of lubricants with proper microstructure additives by which the bearing life can be increased.
