“…The influence of the Frank-Kamenetskii critical parameter (δ) on the thermal explosion of flammable gas containing fuel droplets was investigated in. 24 They showed that the ignition time decreases as (δ) increases. The thermal explosion of a two-phase poly-disperse combustible mixture was examined.…”
