Outline
Based on two phase flow model of interior ballistics, considered that the weight of ignition charge is comparable with the secondery charge and many of its products are solid, the so called four phase flow model of interior ballistics adaptive to the combustion process in the electric squib has been established. In the model, gas products, solid products, ignition charge and secondery chare, all be taken as a phase, each of them is described by mass, momentum and energy equation, and they are related by mutual actions, which are the source terms in the before-mentioned equations. Caculated result by the model is in agreement with the test of the electric squib. This shows that the model describes reasonably the combustion process in the electric squib, and can be as an assistant tool for evaluating of the performance of electric squib.
