Fig. 4.28a,b. Slicethrough the simulation
box in the xz-plane showing the nutrient distribution in two successivegrowth
stages in the bidirectional flow experiment in which Pe is set to the value
0.015 (diffusion dominates). The flow is
directed from top to bottom in (a) and
directed from bottom to top in (b) .

experiment. Pe is set to the value 0.015 (diffusion dominates),
and flowis directed from the left to the right.
