Fick's Second Equation

#Physics
Analogous to Ohm's Law in electrostatic

$\displaystyle \frac{\partial C }{\partial t}=\frac{\partial^2 C}{\partial x^{2}}$

• $\displaystyle C$ is concentration of substance in fluid

$\displaystyle \frac{\partial C }{\partial t}=D\nabla ^{2}C$

• 3D version

$\displaystyle \frac{\mathrm{d}c_{n} }{ \mathrm{d}t}=k_{-}\nabla ^{2}c_{n}$

• For nucleation
