Lubrication in cold rolling: Elasto-plasto-hydrodynamic lubrication [PDF]
, 1993 A model has been developed with respect to hydrodynamic lubrication in cold rolling. The basic model describes the configuration of a rigid, perfectly plastic sheet rolled by a rigid work roll.

Hydrodynamic interactions in dense active suspensions: from polar order to dynamical clusters [PDF]
, 2017 We study the role of hydrodynamic interactions in the collective behaviour of collections of microscopic active particles suspended in a fluid. We introduce a novel calculational framework that allows us to separate the different contributions to their ...

Influence of short grooves on hydrodynamic lubrication of textured infinitely long sliders
Advances in Mechanical Engineering, 2018 The influence of geometrical parameters of the short grooves on the hydrodynamic lubrication is studied in this article. Based on Reynolds equation and Jakobsson–Floberg–Olsson cavitation theory, an analytical model is developed to investigate the ...
