Title:
CFD analysis and experimental study on the effect of oxygen level, particle size, and dust concentration on the flame evolution characteristics and explosion severity of cornstarch dust cloud deflagration in a spherical chamber 
Abstract:
To clarify the effect and mechanism of oxygen supply, particle size, and dust concentration on the flame propagation behaviours and explosion characteristics of cornstarch dust cloud, a 3D numerical simulation for simulating the explosion process of cornstarch dust cloud were conducted and verified with experimental data using a 20-L sphere. Next, flame behaviours and explosion parameters under different conditions were investigated using numerical calculation and experimental observation. Resul...    »
