  To capture the dynamic behaviors of reaction-subdiffusion in flow fields, in
the present paper we analyze a simple monomolecular conversion A $\rightarrow$
B. We derive the corresponding master equations for the distribution of A and B
particles in continuous time random walks scheme. The new results are then used
to obtain the generalizations of advection-diffusion reaction equation, in
which the diffusion and advection operators both depend on the reaction rate.
