Flocculation Tank with Three Baffles Turning


 The simplification of a single baffle turn eliminates important behavior within the flocculator. Multiple baffles enable separation regions to interact with each other. The velocity magnitude plot below in Figure 1 displays how the flow before separation at the second turn is not uniform and moves fastest at the edge of the baffle. The faster moving fluid can't turn fast enough and impinges on the edge of the third baffle. The contours of turbulence disspation rate illustrate in Figure 2.

Flocculation Tank with Five Baffles Turning

The five baffle turning 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. Image Added

The flow obviously relates to the geometry of the problem. Altering the geometry of the problem will result in different flows.
