Using the Landau-Levich law to seal seams in waterproof clothing
… a film of a thickness governed by the Landau-Levich law. The equation governing Landau-Levich behavior is combined with equations describing hole geometry to develop a phase space describing the fluidic and geometric properties necessary to seal a hole. A manual proof of concept test is …

Vibrating lubricant-infused porous surface for enhanced liquid droplet transport
… film follows lubrication theory and the Landau-Levich law — there is a zone of capillary pressure-driven flow inside the lubricant wetting ridge around the droplet base when the capillary number is much smaller than one. The viscous dissipative force, which resists this capillary suction of …

Test analysis & fault simulation of microfluidic systems
… test methods, namely, impedance spectroscopy and Levich electro-chemical sensors have been investigated as general methods of microfluidic test, each of which has been shown to be sensitive to a multitude of fault. Each method has successfully been implemented within the simulation environment and …

Model-based Experimental Design in Electrochemistry
… the latter, most notably the derivation of a Levich-like expression for the limiting current. The results are then used to compute corresponding identifiability functions for each of the above configurations. Potential effectiveness of each device in recovering kinetic parameters are …

Momentum Effects: Essays on Trading Rule Returns in G10 Currency Pairs
… The chapter builds on the work of Pojarliev and Levich (2008, 2010), who dissect the returns of active currency managers by applying a multiple ordinary least squares (OLS) regression to currency fund returns. Where the chapter differs is in the specification of the dependent variable, which is …

Modeling and simulation of liquid microlayer formation and evaporation in nucleate boiling using computational fluid dynamics
… computations of the transition to a Landau-Levich-Derjaguin film in forced dewetting to inform the onset of microlayer formation in nucleate boiling. These contributions(a) (b) (c) (d) bridge a significant gap in our understanding of how boiling works and can be modeled at the microscopic …

The Response of Antarctic Ice Streams to Tidal Forcing
… constitutes an elastic analogue to the Landau-Levich problem, where the thickness of the deposited fluid layer depends on the elasticity of the overlying sheet. I contrast the slow dynamics of the outgoing tide with the relatively fast dynamics of water entering the subglacial cavity during the …

Biological and biomimetic oxygen electro-reduction by enzymes
… transferred as calculated from Koutecky-Levich and charge/mass balance analysis. The pH study of Fe-phenanthroline provides a deeper understanding of how pH influences the mechanism and kinetics of oxygen reduction in non-PGM catalysts.

The “Apparent” Diffusion Coefficient of Electrons Through a Nafion Membrane
<p>The hydrogen/oxygen fuel cell is a greener, more efficient energy solution. However, there are many problems with the fuel cell including storage, infrastructure, cost, the oxygen reduction reaction, and the durability of the proton exchange membrane (PEM). The PEM is not only used as the …

Multi-scale morphology development in solution coated conjugated polymers
… undergoes transition from evaporation to Landau-Levich regime on medium to high surface energy substrates. We constructed the dimensionless morphology number by multiplying evaporative Peclet number with modified capillary number to quantitatively describe the film-to-strip morphology transition. …
