pure oxygen combustion
 

Problem: high temperature(4000~5000K)

I has known max. 3500K in case of pure oxygen combustion. would you comment and advise about this problem?

---------------- setting ----------------------

#geometry: 3D furnace calculation(propane-pure oxygen combustion) - non premixed type

#turbulent model: RNG-model, no selection of viscous heating button and otherwise

#combustion model: finite-rate/ eddy dissipation model

#combustion coeff. : after selecting propane-air(2 step), remove N2.

#properties: volume-weighted mixing law(Cp)

thermal conductivity and viscosity :ideal-gas mixing law

mass diffusion : constant(default)

#Boundary : symmetric BC, pressure-outlet, mass-inlet
