Thinning fluid film

WebMar 25, 2002 · Consider the three-dimensional flow of a viscous Newtonian fluid upon an arbitrarily curved substrate when the fluid film is thin as occurs in many draining, coating and biological flows. We drive the lubrication model of the dynamics of the film expressed in terms of the film thickness. The comprehensive model accurately includes the effects ... WebA thin film is a small gap of fluid between moving surfaces. This thin layer of fluid can alter the structural response of the structure by adding stiffness and/or damping to the system. Movement normal to the gap produces a squeeze film effect (modeled with FLUID136 and FLUID138 elements). Movement tangential to the gap produces a slide film ...
