Hi
I want to model auto-ignition of a gaseous hydrogen jet issue in a hot air co-flow. which model is better? Composition PDF Transport model or non-premixed combustion? If i use the PDF model in fluent, the auto-ignition model should be active too ? |

Dear sir
I am trying to do same autoignition for mixture heptane/N2/O2/AR: 0.562/58/30/10 mole fraction ratio But unable to do it by any method i tried its not igniting in chemical equilibrium mode, flat temp I tried use the flamelet - created steady solution by the unsteady is not happening due to error regarding the largest mixture fraction ... Can u suggest to which model to refer in species |
