Contribution to the modeling of a liquid film flowing down inside a vertical circular tube.

Ce comportement est surprenant, dans la mesure o` u nous avons choisi un fluide mouillant parfaitement la paroi en conditions isothermes : ` a l’´echelle nanom´etrique, au plus pr`es

Dans les deux cas, les déformées présentent des oscillations dans le sens circonférentiel, mais pas dans le sens axial (figure 3c), ce qui donne à la structure déformée

for the decrease in threshold for the instability: the advection by the base flow in the framework of the wave, proportional to sc−U 0 d is stronger for a shear-thinning

The nonlinear dynamic problem of a disturbed film flowing down a flat vertical (or inclined) wall has. been considered by many authors, starting from the pioneering

The equilibrium shape of a looped edge dislocation in a vertical smectic-A film allows the determination of its line tension: in agreement with theoretical predictions, it is found

In this situation, it has been shown that particles dispersed in a wetting fluid are entrained in the coating film when the thickness at the stagnation point is larger than a

For foam film supported on a rectangu- lar solid frame, when the interface presents a low resistance to shear, the drainage dynamics involves a complex flow pattern at the film

A green laser (beam waist 360 lm, k ¼ 532 nm) impinges at nearly normal to the prism and then gets totally reflected on the glass/air interface, since the angle of incidence h
