pointed downward.
remember- the goal of the secondary air is not to add oxygen ,is to force the flames to a better direction (downward in this case) and to mix the laminar flow.

Probably similar shape to many vacuum cleaner attachments that create better vacuum through the shape of attachment?

in a P channel classic you might use the laminae to restrict flow and increase the speed. You may be mounted inside the channel in the hearth according to the shape give the direction to the flow in order to characterize the flame

Hmmm. Wonder what would happen if there were no riser and the port emptied into a horizontal afterburner the same height as the port? Would the roof of that chamber shape the flame in a similar way without the extra oxygen?

I am not in complete understanding about the structure of the chet portal. But if the p channel's function is not to supply O2, if you are building a barrel covered batchbox, could you change (shorten) the p channel so that it is entirely contained within the barrel and is supplying preheated combusted air from inside the barrel? I'm not disputing the value of the chet portal, but the p channel seems simpler for me to implement. And a shortened p channel seems even simpler.

all the idea of using combusted air from inside the barrel is new and not reliable yet. if you prefer the P channel, just taper it in the end.

in theory if not needed supply of oxygen from the P channel you could use the gas inside the bell. Shilo what makes you say that this solution is not stable? perhaps the flue gases alter the combustion of the unburnt gases inside the riser?

no one measured the pressure at the port and at the barrel. we done some tests but we aren't sure what the best place to take the air from.
