Query: Convection-Diffusion-Reaction equation with similarity solutions   We consider similarity solutions of the generalized
convection-diffusion-reaction equation with both space- and time-dependent
convection, diffusion and reaction terms. By introducing the similarity
variable, the reaction-diffusion equation is reduced to an ordinary
differential equation. Matching the resulting ordinary differential equation
with known exactly solvable equations, one can obtain corresponding exactly
solvable convection-diffusion-reaction systems. Some representative examples of
exactly solvable systems are presented. We also describe how an equivalent
convection-diffusion-reaction system can be constructed which admits the same
similarity solution of another convection-diffusion-reaction system.
