Effects of small surface tension in Hele-Shaw multifinger dynamics: an analytical and numerical study
E. Paune, M. Siegel, J. Casademunt
We study the singular effects of vanishingly small surface tension on the dynamics of finger competition in the Saffman-Taylor problem, using the asymptotic techniques described in…
Dynamical Systems approach to Saffman-Taylor fingering. A Dynamical Solvability Scenario
E. Paune, F. X. Magdaleno, J. Casademunt
A dynamical systems approach to competition of Saffman-Taylor fingers in a channel is developed. This is based on the global study of the phase space structure of the low-dimension…
Sidebranching induced by external noise in solutal dendritic growth
R. Gonzalez-Cinca, L. Ramirez-Piscina, J. Casademunt +1
We have studied sidebranching induced by fluctuations in dendritic growth. The amplitude of sidebranching induced by internal (equilibrium) concentration fluctuations in the case o…
Systematic weakly nonlinear analysis of interfacial instabilities in Hele-Shaw flows
E. Alvarez-Lacalle, J. Casademunt, J. Ortin
We develop a systematic method to derive all orders of mode couplings in a weakly nonlinear approach to the dynamics of the interface between two immiscible viscous fluids in a Hel…
Viscous fingering in liquid crystals: Anisotropy and morphological transitions
R. Folch, J. Casademunt, A. Hernandez-Machado
We show that a minimal model for viscous fingering with a nematic liquid crystal in which anisotropy is considered to enter through two different viscosities in two perpendicular d…
Two-finger selection theory in the Saffman-Taylor problem
F. X. Magdaleno, J. Casademunt
We find that solvability theory selects a set of stationary solutions of the Saffman-Taylor problem with coexistence of two \it unequal \rm fingers advancing with the same velocity…
