Hello Everybody, I'm modeling a fire located in a room and I want to see the interaction between the ventilation system and the spreading of the fire and smoke.My model is simple a room with 2 inlets and 2 outlets and a fire source located into the middle of the room.I have checked into the Ansys support for this problem and found two text files.
Modeling Smoke Visibility in CFD
I have choose to make the combustion fire model, but when I start to enter the source code into CFX I stucked at the begining when I try to add the Boundary Floor I cannot add the Equation source CH4Does anybody has idea how to made this source code to the model. Sw/- the model X...- combustion source code OC9ww/- inert source code Thank you. Modal 100 dollar untuk forex. Inert Fire Modelling -------------------- # # Fire Source # For inert fire simulations a source of heat is added to a source volume.This type of simplification is appropriate if accurate predictions of the shape of the flame and the near field region of the fire are not important.The Fire Efficiency parameter determines how much of the fire power is added as heat.
Fire Safety and Smoke Management with CFD Analysis.
It can be used to account for the combustion efficiency.In well ventilated fires with clean burning fuels this is likely to be quite high (0.9-1.0). Radiative heat fluxes from the fire zone can be significant.The total fire power will be split between the radiative and convective heat fluxes from the fire zone.
