Paper Abstract

We study the reaction front for the process A + B → C in which the reagents move subdiffusively. We propose a fractional reaction-subdiffusion equation in which both the motion and the reaction terms are affected by the subdiffusive character of the process. Scaling solutions to these equations are presented and compared with those of a direct numerical integration of the equations. We find that for reactants whose mean square displacement varies sublinearly with time as (r2) ~ tγ, the scaling behaviors of the reaction front can be recovered from those of the corresponding diffusive problem with the substitution t → tγ.
