Another Rebreather Scrubber Thermokinetic Simulation

Compared to the previously posted video of a segment of a rebreather scrubber, this video shows a much larger, and therefore more realistic scrubber with axially aligned, CO2 rich gas flow passing from left to right. Due to the larger size of the simulation space, more widely distributed heat patterns are noticeable, as are fluctuations in heat. The flow of those fluctuations are most noticeable along the simulated boundary of the cylindrical scrubber bed.

The assumptions of this simulation are that CO2 production (diver workload) is constant throughout the simulation run, ventilatory flow through the canister is constant, the surrounding water temperature is constant at 50° F, and the canister was chilled to the water temperature before the “diver” started breathing through it.

The previous simulation conditions were similar except that the canister was toasty warm prior to immersion in frigid water.

To fully appreciate the fine detail of the imagery, click on the video frame then expand the video to full screen size (lower right symbol immediately after “You Tube”) and play back in 1080p High Definition mode.
