We consider a two-dimensional model of a vapor bubble between two horizontal parallel boundaries held at different temperatures. When the temperatures are constant, a steady state can be achieved such that evaporation near the contact lines at the hot bottom plate is balanced by condensation in colder areas of the interface near the top. The dynamic(More)
The objective of this work is to study the fundamental instability behind the crown formation in the problem of drop splashing on a pre-existing liquid film. Based on experimental and theoretical insights, we demonstrate that the most plausible instability mechanism is of the Richtmyer-Meshkov type associated with a nearly impulsive acceleration of the(More)
In this work we present an experimental study of deviations from the classical Landau-Levich law in the problem of dip coating. Among the examined causes leading to deviations are the nature of the liquid-gas and liquid-solid interfaces. The thickness of the coating film created by withdrawal of a plate from a bath was measured gravimetrically over a wide(More)
We present a new analytical solution for the static shape of a two-dimensional droplet in equilibrium with a surrounding thin film on a solid substrate. The modeling includes the effects of capillarity and disjoining-conjoining pressure accounting for intermolecular forces between the solid and the liquid. We derive new analytical solutions for the shape of(More)
This paper investigates the effect of evaporation on the shape of liquid/vapor interfaces in small-scale systems. Vapor bubbles are generated due to localized heating in a small-sized channel (with an inner dimension of 3x3x200 mm) filled with pentane, for which heat fluxes and temperature distributions are simultaneously measured. The length of the(More)
