Hi, there.
I would like to investigate the velocity of air premixed flame in bunsen configuration.
Here is the settings that I used for the result:
1. Methane-air as my material.
2. Using 0.0905 CH4, 0.19 O2 for my air-fuel velocity inlet, pure nitrogen for coflow velocity inlet and 0.21 O2 for pressure outlet.
3. Turn off volumetric reaction for cold reaction, patching with 3000K at the region between coflow and air-fuel inlet, then run for volumetric reaction.
However, my result is totally different to what I expected to get (shown as the attached image).
Static Temperature (new meshing model, patch 3000C).PNG
Is there any improvement that I can make until this step?
