Scaling analysis of diffusion equation
Did you know?
WebThe diffusion equation is a partial differential equation. The unknown quantity is a function C ( x, t). To complete the problem statement you need to specify an initial condition (at t = 0) and boundary conditions. I'm guessing that your boundary conditions are at infinity, so we take C ( x, t) → 0, x → ± ∞.
