| I've had some interesting thoughts on this, I think most designs from from the centre outwards, which means that as the scrubber is used up, the theoretical "depth" of the reaction front gets thinner as the diameter expands.
However, consider this. For a typical dive provile, you go deep at the start, and end up shallow at the end, so it makes sence to have your scrubber working most efficiently* at the beginning of it's life. Deeper = higher gas density, which in an axial scrubber would mean "deeper" reaction front, but in a radial, working from the outside in, because of the larger diameter, the "depth of the front" might be thinner.
* by most efficiently, I mean "most tolerant to high gas densitys and flowrates and minimal breakthrough potential"
This is all theoretical straight from my head, so it's likely that there are people out there with much more useful/empirical evidence..... |
