Hi everybody,
I am trying to simulate the deflagration-to-detonation transition process with FLUENT. The model is a 2D, axisymmetric pipe with one closed end and the other end is vent. The species transport and eddy-dissipation model is used to simulate the combustion process. I used outlet-vent in boundary condition and specified the value of pressure (0.098 atm) in order to burst the vent. After initializing the problem with stoichiometric CH4/O2 mixture occupying the whole pipe, I patch a region of high temperature (2000K) to the closed end of the tube to simulate a spark ignition. However, the result is unreasonable. I would be much appreciated if anyone could enlighten me on the possible explanation of the venting configuration in FLUENT Regards, Hazwani |
