Convergence to the Reynolds approximation with a double effect of roughness [PDF]
We prove that the lubrication approximation is perturbed by a non-regular roughness of the boundary. We show how the flow may be accelerated using adequate rugosity profiles on the bottom.

Rheology near jamming - the influence of lubrication forces
We study, by computer simulations, the role of different dissipation forces on the rheological properties of highly-dense particle-laden flows. In particular, we are interested in the close-packing limit (jamming) and the question if "universal ...

Positive commandable oiler for satellite bearing lubrication [PDF]
The results of a feasibility study showed that on-orbit commandable lubrication of ball bearings can be accomplished by direct oil application to the moving ball surfaces.

Propulsion Mechanisms for Leidenfrost Solids on Ratchets [PDF]
We propose a model for the propulsion of Leidenfrost solids on ratchets based on viscous drag due to the flow of evaporating vapor. The model assumes pressure-driven flow described by the Navier-Stokes equations and is mainly studied in lubrication ...

Breakup of diminutive Rayleigh jets [PDF]
Discharging a liquid from a nozzle at sufficient large velocity leads to a continuous jet that due to capillary forces breaks up into droplets. Here we investigate the formation of microdroplets from the breakup of micron-sized jets with ultra high-speed
