Abstract:
Flame behaviours and explosion severities are vital for conducting risk evaluations, obtaining a dynamic control, and determining propagation mechanisms of aluminium dust explosions. In this study, a three-dimensional (3D) mathematical framework and a computational fluid dynamics (CFD) model were established to numerically reveal the dynamic evolution of flame morphology, deflagration severities, and heterogeneous combustion properties of an explosion due to an aluminium dust–air mixture by usin...     »
