Long-scale evolution of thin liquid films
TL;DR: In this article, a unified mathematical theory is presented that takes advantage of the disparity of the length scales and is based on the asymptotic procedure of reduction of the full set of governing equations and boundary conditions to a simplified, highly nonlinear, evolution equation or to a set of equations.
Journal ArticleDOI
Flow phenomena in rocks : from continuum models to fractals, percolation, cellular automata, and simulated annealing
TL;DR: In this article, theoretical and experimental approaches to flow, hydrodynamic dispersion, and miscible and immiscible displacement processes in reservoir rocks are reviewed and discussed, and two different modeling approaches to these phenomena are compared.
Journal ArticleDOI
A review of immiscible fluids in the subsurface: properties, models, characterization and remediation
James W. Mercer,Robert M. Cohen +1 more
TL;DR: In the past few years, as hazardous waste sites have been studied more often and in more detail, immiscible fluids have been encountered in the subsurface with greater frequency as discussed by the authors.
Journal ArticleDOI
Pattern selection in fingered growth phenomena
TL;DR: In this article, the authors survey recent theoretical work which elucidates how such systems arrive at their observed patterns, focusing on dendritic solidification, simple local models thereof, and the Saffman-Taylor finger in 2D fluid flow.
Journal ArticleDOI
Harnessing Surface Wrinkle Patterns in Soft Matter
TL;DR: In this paper, two distinct approaches for wrinkle formation, including mechanical stretching/releasing of oxide/PDMS bilayers and swelling of hydrogel films confined on a rigid substrate with a depth-wise modulus gradient, are discussed.

Viscous flows in two dimensions
TL;DR: In this paper, the Saffman-Taylor equations for the displacement of one fluid by another in a two-dimensional geometry (a Hele-Shaw cell) are discussed.
Journal ArticleDOI
Radial fingering in a Hele Shaw cell
TL;DR: The results of experiments involving instability, known as fingering, in a circular Hele Shaw cell with inward and outward flow are presented in this article, and an approximate equation for the growth of fingers is proposed.

Stability of miscible displacements in porous media: Rectilinear flow
C. T. Tan,George M. Homsy +1 more
TL;DR: In this article, a theoretical treatment of the stability of miscible displacement in a porous medium is presented, where the base state of uniform velocity and a dispersive concentration profile is time dependent, leading to predictions of the growth rate.
