This is a follow up question to "Organic Marbles" answer to my earlier question about the atlas rocket exhaust nozzle, regarding the Apollo F1 thrust nozzles having metal baffles/fins inside to prevent the exhaust from spinning around inside the nozzle and exploding the engine/rocket.
My question is, were the nozzle exhaust pipes on the Atlas rocket engines, and the baffles installed inside of the F1 nozzles of the Saturn V first stage, dealing with the same issues of safely venting exhaust gases away from the rocket, or are they different issues.
