... shear thickening and then proceeds to shear thinning. In this regime, the viscosity of the fluid is large enough that the contribution of the foam and the fluid-structure interaction to the stress response of the fluid-filled foam can be neglected. An analytically tractable lubrication model...

... ppi to 90 ppi and strain rates varying from 2.5 × 10 − 3 to 10 1 s − 1 well. The full model can also be well approximated by a simpler model, based on the lubrication approximation, which is applicable to analyses where the dimension of the foam in the direction of fluid flow (radial) is much greater...

...E. Mitsoulis; S. Sofou The lubrication approximation theory (LAT) is used to provide numerical results for calendering a sheet from an infinite reservoir. The Herschel–Bulkley model of viscoplasticity is employed, which reduces with appropriate modifications to the Bingham, power-law, and Newtonian...

...A. Lavrov Flow of bi-viscous fluid, i.e., non-Newtonian fluid with the shear stress versus shear rate function composed of two straight segments, from a borehole into a nonpropagating deformable horizontal fracture of circular shape was modeled within the lubrication approximation. The volume...

...J. Tichy Continuum based methods are traditionally thought to be of little value in describing boundary lubrication, or the mode of lubrication in molecular scale films that may occur at asperity interactions during the sliding of nominally flat surfaces. There is considerable experimental evidence...
