Flame sheet starting estimates for counterflow diffusion flame problems
The authors develop a flame sheet starting procedure for the numerical modelling of laminar counterflow diffusion flame problems. The model couples the equations of mass and tangential momentum with a Shvab- Zeldovich equation to provide estimates for the mass flux in the transverse direction, the similarity function, the temperature and the stable major species in the flame. The procedure is formulated for both the porous cylinder and cylindrical double-jet configurations. Application of the model to two laboratory methane-air flames reveals the effectiveness of the procedure in generating starting estimates for such problems.
