They can be used to solve for the diffusion coefficient, D.Fick's first law can be used to derive his second law which in turn is identical to …
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… WebAug 18, 2024 · The solution to this differential equation is: f = A e − u 2 4. where A is a constant of integration.
