High soot yield in pyrosim
Web1 day ago · I am trying to model a room fire in Pyrosim and want to change the soot yield. Does anybody know how to set a soot yield to 0.2 kg/kg? Thanks, Robert. Logged Timo. … WebApr 20, 2009 · The way PyroSim categorizes surfaces, the only surface type that uses reactions is the "Layered" type. If you use one of the other surface types (e.g. Burner), you'll get a SURF record in your FDS input file, but no accompanying MATL or REAC records.

It's under the Byproducts tab in the Reactions dialog. You can set it explicitly. Smokeview shows the soot as smoke, but I don't know how you'd measure it quantitatively. I think you could just say it's 0.01 though. Logged Swissi Member Posts: 15
