In physics, chemistry, and materials science, percolation (, first coined in the 1840s by Edward Loysel) refers to the movement and filtering of fluids through porous materials. It is not described by Darcy's law. Broader applications have since been developed that cover connectivity of many systems modeled as lattices or graphs, analogous to connectivity of lattice components in the filtration problem that modulates capacity for percolation.
