Drop-in Baffle diagram -for discussion

The thread about the baffle inserts in the “for sale” section got my wheels turning and I spent a little time drawing this diagram to work through my thoughts. It seems to me that we need some acute angles to not only break up the air flow, but more importantly the sound wave.

The 90 degree angles should do this by first giving resistance to the air flow, and secondly directing the sound wave back onto itself. Also seems to me that it would have a greater effect with each baffle baffle the sound/pressure wave passed through prior to exiting the end cap.

I am sure there is a balance point to be achieved between number of baffles vs. free space between baffles. Think of a fireplace flue vs. hearth area (ever hear your fireplace chug like a locomotive?) or a two-stroke motors expansion pipe size vs. cylinder displacement, etc.

I am no fluid dynamicist, but it makes sense to me? Any thoughts from the rest of the woodshed tinkerers/armchair engineers?
