Pattern selection in two-dimensional dendritic growth
EA Brener, VI Mel'Nikov - Advances in Physics, 1991 - Taylor & Francis
We present an analytical treatment of the problem of pattern selection in a fully non-local
symmetrical model of dendritic crystal growth. Simplifications of mathematical equations are …

A numerical analysis of dendritic and cellular array growth: the spacing adjustment mechanisms
SZ Lu, JD Hunt - Journal of Crystal Growth, 1992 - Elsevier
A numerical model has been used to describe the steady and the non-steady growth of array
cells and dendrites in a moving linear temperature field. It was found that the four parameter …

Surprises in viscous fingering
S Tanveer - Journal of Fluid Mechanics, 2000 - cambridge.org
In this paper, we review some aspects of viscous fingering in a Hele-Shaw cell that at first
sight appear to defy intuition. These include singular effects of surface tension relative to the …

Viscous finger widening with surfactants and polymers
We study the viscous fingering instability which results from a competition between capillary
and viscous forces. We show that for two different systems the instability is modified …

Viscous fingering in complex fluids
Viscous fingers form when in a thin linear channel a fluid pushes a more viscous fluid. The
instability of the interface results from a competition between viscous and capillary forces …

Perturbing Hele-Shaw flow with a small gap gradient
H Zhao, J Casademunt, C Yeung, JV Maher - Physical Review A, 1992 - APS
A controlled perturbation is introduced into the Saffman-Taylor flow problem by adding a
gradient to the gap of a Hele-Shaw cell. The stability of the single-finger steady state was …

Pushing a non-Newtonian fluid in a Hele-Shaw cell: From fingers to needles
We make a theoretical study of the finger behavior of a simple fluid displacing a non-
Newtonian fluid confined in a Hele–Shaw cell. We study the Saffman–Taylor instability when …
