Diffusion with shrinking in slabs: An approximate analytical solution

The equation for diffusion in a shrinking slab with constant diffusion coefficient is solved by the method of moments. Good agreement with the numerical solution of the same equation is found, as well as with the numerical solution of a differential equation recently proposed for this kind of proble...
