So I completed my first build of a smoker. Works great. I don't see any issues with its airflow so far. Now I'm working on plans for a bigger smoker. Something about the size of a Backwoods Competitor. Here are my questions: I would assume the CFM should slowly decrease throughout the smoker (from vent intake to hollow wall to cooking chamber to chimney) which would cause forced convection. Is this correct? And if so is there a rule of thumb as far as how much it reduces each step? As far as the air flow... would you want to make it flow as smooth as possible? I guess what I'm asking here is..does turbulence have an effect on proper air flow/smoke? Can turbulence cause smoke to "roll" inside the cooking compartment causing "stale" smoke? I don't know if these are stupid questions or not... or even if the answers have much effect on the cooking process itself. I'm just considering some variables I see and using my mechanical abilities to iron them out on my next build if it's lucrative to the build. Thanks ahead of time!
