Figures 5 through 7 along with Table 5 present the results obtained from the countercurrent flow in the simulation model.
In the countercurrent flow regime, the fluid moves through the vent in two distinct streams, with one going up and the other going down.
While conventional wet scrubbers use a countercurrent flow, in which the flue gas rising from the base of the scrubber passes upward through the falling slurry spray, the Pure Air version uses a high-velocity, co-current flow.
Fully operational, cupolas exhibit an efficient countercurrent flow with the hot gases preheating the charge as they percolate up through successive charge layers and out the stack.
They are ranging from different orientations as vertical, horizontal, or inclined, different geometries as pipes, channels, rod bundle, and flow configurations as cocurrent or countercurrent flow. This correlation, although general, lacks the model specificity that is required for an accurate prediction [22].
In the laboratory, I saw students measure conductivity and the clearance of sodium molecules across their constructed semi-permeable membranes within designated periods of time using countercurrent flow.
Plateflow is said to offer true countercurrent flow, maximizing mean temperature difference between the fluids.
This recirculation flow (i.e., a countercurrent flow), which is shown in Figure 17(b), did not appear in the 1D analysis using the MARS code.
