Lecture 15: Diffusion (Part 3, Advection-Diffusion Equation and Solutions)

In this lecture, we derive the advection-diffusion equation for a solute. We then obtain analytical solutions to some simple diffusion problems. In particular, we look at the Green's function for 1-D diffusion problem in infinite domain.

please be clear with language ,what you have told in between 38 and 43 seconds is not clear.

I am saying "the mass flux is related to gradient in concentration..." I thought it was pretty clear.

[@pushpagautam1700]

Thank you for the response ,I understood you were talking about the change in concentration .probably it would be gradient of concentration instead of "in".Thank you again
