The advective diffusion equation
In nature, transport occurs in fluids through the combination of
advection and diffusion. The previous chapter introduced diffusion and derived solutions to
predict diffusive transport in stagnant ambient conditions. This chapter incorporates advection into our diffusion
equation (deriving the advective diffusion equation) and presents various methods to solve the resulting partial
differential equation for different geometries and contaminant conditions.
The Appendix B (PDF)
presents solutions to the advective diffusion equation (with
reactions) for various source conditions and geometries.
