On the Flow Dynamics of Polymer Greases

In this paper, the flow dynamics of polymer greases was investigated using micro-particle image velocimetry. Polymer have a different thickener structure, compared to widely used lithium-based greases, and they well-known ability release oil. How these properties affect grease deformation its is corresponding behavior lithium complex with same consistency. Two main tests were carried out, where velocity profiles in straight channel measured analyzed, evolution during transition period from no-flow fully-established measured, respectively. It found that grease. This indicates internal structure bleed oil strong influence on global scale, which turn entails other lubricating abilities for two types.
