Webto combine Fick’s rst law with the general equation of mass conservation, namely @ tC+ rJ D= 0 (2) where ris the divergence operator. In the case where Dis a constant, this leads to @ tC= D C (3) which is usually referred to as Fick’s second law. This is the equation that has to be solved if you want to calculate a concentration pro le.

Fick's 1st and 2nd law

WebThe second law of diffusion is a linear equation with the dependent variable being the concentration of the chemical species under consideration. Diffusion of each chemical species occurs independently. The mass transport systems described by Fick's second law are easy to simulate numerically.

WebFick’s first law tells us HOW MUCH flux to expect. Fick’s second law gets into more detail, telling us the rate at which concentration is changing at any given point in space. This law takes the form of a “partial differential equation”, that is, an equation that allows us to solve for rates involving both time and space. harley nassauWebFick's 2nd law of diffusion Consider diffusion at the front and rear surfaces of an incremental planar volume. Fick's 2nd law of diffusion describes the rate of accumulation (or depletion) of concentration within the volume as proportional to the local curvature of the concentration gradient. harley mieten miamihttp://www-eng.lbl.gov/~shuman/NEXT/MATERIALS&COMPONENTS/Xe_damage/ficks2ndlaw.pdf harley osakeWebwas elaborated by Joseph Fourier in 1822, Adolf Fick in 1855 and by Albert Einstein in 1905.
