i'm curious how hot the fluid would actually get since it is nowhere near a heat source until it is pumped out the nozzle. There wouldn't be any preheating. That is not to say jet exhaust isn't hot enough to flash boil it at the exit point, just wonder if that is too late. I need to find out at what temperature it overheats and starts to boil. I also wonder if a little extra mineral oil would raise the boiling temp to the right point? I need a science and chemistry type to analyze what's in smoke fluid and recommend a blend. This wouldn't be an issue if commercial smoke fluid wasn't so overpriced.
Fortunately shot cooling a pipe will not be an issue as my smoke system is in a Boomerang Elan without a stainless steel pipe. I would be shooting the fog fluid pretty much at the last 2 inches of the rear fuselage.
