【 摘 要 】

In this research an analytical study has been conducted to determine flame propagation speed and quenching distance of aluminum dust particle in an oxygenated medium with different neutralized gas including nitrogen, argon, and helium which acts as the oxidizer carrier gas. Flame propagation speed as a function of aluminum dust cloud concentration has been studied based on a thermal diffusion model. Additionally quenching distance for different dust particle concentration in the intended neutralize gas is investigated. Reasonable agreement between the present analytical model and experimental results reported in literature has been observed in terms of flame propagation speed in different dust concentrations.
