Interface instability of two-phase flow in a three-dimensional porous medium

|
By Kevin Pierce, Paula Reis, Per Arne Rikvold, Joachim Falck Brodin
| Physical Review B
We present an experimental study of immiscible, two-phase fluid flow through a three-dimensional porous medium consisting of randomly packed, monodisperse glass spheres. Our experiments combine refractive-index matching and laser-induced fluorescence imaging to resolve the morphology and stability of the moving interface resulting from the injection of one fluid into another.

Multicritical bifurcation and first-order phase transitions in a three-dimensional Blume-Capel antiferromagnet

|
By Daniel Silva, Universidad Simón Bolívar, Gloria M. Buendía, Per Arne Rikvold
| Physical Review B
We present a detailed study by Monte Carlo simulations and finite-size scaling analysis of the phase diagram and ordered bulk phases for the three-dimensional Blume-Capel antiferromagnet in the space of temperature and magnetic and crystal fields (or two chemical potentials in an equivalent lattice-gas model with two particle species and vacancies). The phase diagram consists of surfaces of second- and first-order transitions that enclose a “volume” of ordered phases in the phase space.
