What is also not taken into consideration is the gas will travel at different speeds in different parts of the scrubber, for instance gas will travel faster (less dwell time) on the edges where the granules meet the smooth face of the cannister. I think this is less likely in a radial can which may contribute to the supposed better performance of the radial scrubber, at least in terms of duration.

hello dave, this type of non-uniform gas-speed distribution is not taken into account, but this does not influence the 'overall' dwell time, as the scrubber is not a 'gas stocking device'
I will not restart the debate about dwell-time, I made my point and I know what I know...
But as you all know, I never said that a radial can not be more efficiant than an axial, I think we all agree on that. But this is due to other factors, like thermal design (isolation), non-uniform gas-flow due to 'water-stocking' in the sorb, non-uniform sorb packing due to position of the cannister during diving etc etc etc
