I have an issue about ignition of my combustion case in CFX. I am simulating a non-premixed co-axial burner in which gaz is going out in the central axis of a coflow of air. In the geometry of my problem I a flow developing section (tube)for both the gaz (Methane) and the surrounding air. Then both fluid are mixed-up and burn.
I followed the instruction of the manual and I put some values for the product (CO2 and H20)as the initial condition. I either try to introduce some products in my fuel inlet to start the chemical reaction. Unfortunately I haven't got any success up until now.
Is there anybody that would have a suggestion for me on that?
