Viscous fingering in the presence of weak disorder
Eldad Bettelheim, Oded Agam
We consider the problem of viscous fingering in the presence of quenched disorder that is both weak and short-range correlated. The two point correlation function of the harmonic m…
Topological transitions in evaporating thin films
Avraham Klein, Oded Agam
A thin water film evaporating from a cleaved mica substrate undergoes a first-order phase transition between two values of film thickness. During evaporation, the interface between…
Localized Rayleigh Instability in Evaporation Fronts
Haim Diamant, Oded Agam
A qualitatively different manifestation of the Rayleigh instability is demonstrated, where, instead of the usual extended undulations and breakup of the liquid into many droplets,…
Viscous fingering in volatile thin films
Oded Agam
A thin water film on a cleaved mica substrate undergoes a first order phase transition between two values of film thickness. By inducing a finite evaporation rate of the water, the…
Adaptation of Autocatalytic Fluctuations to Diffusive Noise
N. M. Shnerb, E. Bettelheim, Y. Louzoun +2
Evolution of a system of diffusing and proliferating mortal reactants is analyzed in the presence of randomly moving catalysts. While the continuum description of the problem predi…
