The great thing about recognising the hierarchical nature of physical phenomena is that one can work from a level where it is clearly possible to see what is happening, to a level where there are only instrument readings as a guide. Frank, the mention of the hydraulic jump took me back to page 300 of my favorite book on hydraulics  by George Russell, Professor of Hydraulics , MIT, Oct 1941........ and there it was !!!   Reading again of the phenomena brought to mind some interesting experiences in designing for large flume flow measurement and the havoc the HJ can play on an unsuspecting lad that wasn't listening carefully in class but later paid dearly for a first person education on the matter. The  profound importance of your observation of the CF/HF resemblance to the phenomena cannot be overemphasized. I didn't see it, I sensed it but elusive thoughts can play tricks on the meditative process so I discarded it. Thanks for the clue. One puzzle we have is how to cut character into the mixing dispersal exit cone in order to create a  pattern that properly directs the mixed oxidant within  a non standard regime.  BINGO !!  IDEA !!!. Create a hydraulic jump to induce the desired shape of the liquid discharge pattern. Hopefully ,your post may trigger another mind that has CF on the brain < grin> Richard
