Compensated hole-entry Hybrid Journal Bearing by CFV Restrictor under Micropolar Lubricants / Nathi Ram...[et al.]

In this work, the performance of hole-entry hybrid journal bearing compensated by constant flow valve (CFV) restrictor under micropolar lubricants has been numerically simulated. Reynolds equation for micropolar fluid lubricated bearing has been solved with finite element technique. Performance...
