Fluid-like representation of Fickian diffusion

Research output: Contribution to journalArticlepeer-review

Abstract

Here, we show that the fundamental Fickian process of diffusion can be equivalently described by a pressureless, compressible, and irrotational flow dynamics, whose effective force is governed by the divergence of the viscous stress tensor. This brings together the seemingly unrelated processes of mass and momentum transports.
