| Abstract: | In order to study the moving and combustion conditions of powder,and the firing and flame propagation characteristics of the charge structure which has overload protection with ignition by detonation,an axial symmetry two dimension-two phase flow model of the layered charge structure using the ignition by detonation was set up based on the experimental study.The main parameters of ignition process were calculated using programming language,and some typical computed results were listed,such as pressure distribution pattern and solid phase void ratio distribution pattern.From the analysis of firing and flame propagation characteristics of the ignition process,it is concluded that the layered charge structure has nicer flame propagation characteristic. |
