Figure 5: Amount of reagent controls position of maximum of tracer distribution.

Increasing amount of reagent entails a longer time for complete decomposition during which the fluid flow reaches farther along the channel and aggregates tracers into piles (characterized by maximum of n/n0) farther away from the fuel entrance location at x=0. Shift of n/n0-maximum caused by increasing values C0=0.05, 0.1 and 0.2 M is demonstrated for the reaction rates: (a) rmax=1.7 × 10−2, (b) 1.7 × 10−3 and (c) 1.7 × 10−4 mol m−2 s−1.
