The five baffle turns enables high dissipation regions to interact.
case results below shown in Figure 3 reveals a similar velocity profile after each turn. In this case, there is not a high velocity region followed by a high dissipation region, and the flow seems more uniform.
The flow obviously relates to the geometry of the problem. Altering the geometry of the problem will result in different flows with a different distribution of energy dissipationThe geometry to investigate is presented below in the automization of the mesh in GAMBIT. Below is the case where baffle spacing is fixed at .1, and the flocculator height is fixed at .1. This results in a regions of high velocity magnitude, "undeveloped" energy dissipation regions, and a uniform energy dissipation value.

Figure 3: Velocity and Turbulence Dissipate Rate for five turns
This problem is rich in geometric variables, and our investigation found that a larger height baffles is more optimal. Below is the velocity and energy dissipation plots for flocculation height of .4:
Note that the overall epsilon value range (max at .01) is lower than the plot above which has a max of (.05), but has comparatively more uniform distribution for baffles turns 3 and 4.
