Diffusing sphere

The diffusion equation is a parabolic partial differential equation. In physics, it describes the macroscopic behavior of many micro-particles in Brownian motion, resulting from the random movements and collisions of the particles (see Fick's laws of diffusion). In mathematics, it is related to Markov processes, such as random walks, and applied in many other fields, such as materials science, information theory, and biophysics. The diffusion equation is a special case o… WebSep 7, 2024 · Diffusion to Capture. What is the flux of a diffusing species onto a spherical surface from a solution with a bulk concentration C 0?
