Radiation enhanced B-Number

Burning dynamics and in-depth flame spread of wood cribs in large compartment fires

“…Extinction does not follow as the pyrolysis is assisted by radiation [47,53] from the cross-radiating sticks. While the mass transfer number has been extended to incorporate absorption of external radiation in the flame [54], a solution to G H must also consider the interaction of radiation on the flow field, which is not trivial to resolve [55] and can lead to a radiation-controlled regime of fires characterised by strong turbulent flows [56].…”
