Analysis of the laminar flamelet concept for nonpremixed laminar flames

Detailed radiation modeling of a partial-oxidation flame

“…10. Neglecting radiation overpredicts the temperature of the methaneeair flame significantly showing that radiation needs to be considered, which is consistent with previous findings [2,6,7]. Furthermore, OTM/RADCAL yields reasonable agreement with the experimental data.…”

“…It was previously investigated by several groups [2,6,7]. Radiation was found to be important but all groups used the simple OTM/ RADCAL radiation modeling approach.…”

“…Thus, simple radiation modeling assuming an optically thin gas and a fully gray medium failed to predict flame temperatures correctly [4]. However, the same numerical and modeling setup was shown to be suitable for a geometrically similar laminar methaneeair flame [2,6,7].…”

Soot properties of laminar jet diffusion flames in microgravity

“…This involves flames with large variation in scalar dissipation and when the advection term in the transport equation is important. Fortunately, there are emerging models that extend and modify the flamelet model for these particular cases [23][24][25][26][27].…”

“…It has been effective for predicting the structure and radiation properties of buoyant turbulent diffusion flames that have negligible continuum radiation from soot [4,[31][32][33][34][35][36][37][38][39]. When chemistry is sufficiently fast, scalar properties are only functions of the degree of mixing between the fuel and oxidizer owing to the approximate equality of mass and heat diffusivities in flames.…”
