Diffusion-convection problems wherein the species diffusivity is concentration-dependent often provide a differential equation of the following general form: dC where Cis the dimensionless concentration and z is the dimensionless distance. Assume vL/D, is a constant. Assume that C=1 at z= 0, and C=0 when z is very large. Solve the above differential equation and provide an exact analytical equation for C=fA2).
