We have qualitatively explained the experiments of McCloud and Maher for the viscous fingering problem in which an anisotropy in the surface tension parameter was imposed by engraving a grid in one of the plates of the Hele-Shaw cell. We approached the problem in an analytical form by extending...

The phenomenon of Ostwald ripening, where large droplets in a supersaturated solution grow at the expense of small droplets, was theoretically explained by Lifshitz and Slyozov. Modern theories provide extensions of this classic work to the situation where the volume fraction of the phase...
