How to model a heat source for ignition of flame
Hello,
I am simulating a partially premixed flame in fluent with premixed CH4+air mixture and pure-air as coflow. The experiment does not have a pilot for flame ignition hence I am trying to simulate a heat source that can act as an ignition source for the flame. Can anybody let me know how I can do this? Would really appreciate your help. Thanks :) |
Hi Harshad,
Your reaction is the ignition source. In Fluent, you should define the reaction, turn the energy on and determine the reaction enthalpy. |
Hi smhosseini,
Thanks a lot for your reply. I do define my boundary conditions and the appropriate reactions. The flame is not igniting. Actually in the experiments the flame would ignite only with the help of an igniter/propane torch kept on the base of the burner. To model the propane torch I was thinking of having a heat source in the mesh. How can i model a heat source in the mesh? |
Did you read Fluent user guide -> Modeling Partially Premixed Combustion?
