RANS case, kw-sst model, DPM, species transport, DO model. mass flow rate inlet for CH4, wall with thickness and assigning the outside wall temperature as constant. emissivity of wall 0.9, diffusive fraction 1.
pure oxygen.
Flame and combustor wall have the thermal radiation on the burner tip. I try to find out how mch radiation from these two sources, shown in the figure below, the red arrow meaning the radiation from the wall to burner head (the yellow ring).
I try to hand calculate view factor, but there is no straight way to do it. could you give me some suggustion?
