Fick's second law is a special case of the convection–diffusion equation in which there is no advective flux and no net volumetric source. It can be derived from the continuity equation: where j is the total flux and R is a net volumetric source for φ. The only source of flux in this situation is assumed to be diffusive flux: Plugging the definition of diffusive flux to the continuity equation and assuming there is no sourc… WebFick’s 2nd Law •Fick’s 1st law is a response law that can be solved conveniently only under steady–state conditions. •However, the distribution of atoms, C(r, t,), usually depends on both space, r, and time, t.•This makes the concentration a field, because it depends on both time and distance. •An additional physical constraint on the behavior of the … scream rated r 2023
