A Multi-Scale Study of Droplet Collision Dynamics: From Gas Film Lubrication to Liquid Phase Mixing
Binary droplet collision plays an elementary role in dense spray combustion. The collision outcome influences the spray characteristics, for example, the distributions of droplet size and velocity, local mixing rate, etc., and thus the overall combustion performance. In this paper, the dynamics and mixing of colliding droplets are preformed computationally and theoretically. All possible collis...

متن کاملFriction Control in Thin-Film Lubrication
A novel method is proposed for controlling and reducing friction in thin-film boundary lubricated junctions, through coupling of small amplitude (of the order of 1 Å) directional mechanical oscillations of the confining boundaries to the molecular degrees of freedom of the sheared interfacial lubricating fluid. Extensive grandcanonical molecular dynamics simulations revealed the nature of dynam...
متن کاملEnhancing Full-Film Lubrication Performance via Arbitrary Surface Texture Design∗
Minimizing energy loss and improving system load capacity and compactness are important objectives for fluid power systems. Recent studies reveal that micro-textured surfaces can reduce friction in full-film lubrication, and that asymmetric textures can reduce friction and increase normal force simultaneously. As an extension of these previous discoveries, we explore how enhanced texture design...
متن کاملHybrid atomistic-coarse-grained treatment of thin-film lubrication. I.
A technique that melds an atomistic description of the interfacial region with a coarse-grained description of the far regions of the solid substrates is presented and applied to a two-dimensional model contact consisting of planar solid substrates separated by a monolayer fluid film. The hybrid method yields results in excellent agreement with the "exact" (i.e., fully atomistic) results. The i...
