| Abstract: | In this paper the gas solid two phase theory is employed to study the microconvective heating of granuler explosive (HMX) by a semiconductor bridge.The mathematical model of numerical simulation is presented.The MacCormack difference pattern is used to make the numerical simulation.The results of numerical simulation proved that heat deposition by phase change of silicon vapor plays a major part in heating explosive.The effect of initial silicon vapor cloud radius,thickness of SCB,packing density and initial cocentration of condensible in the vapor cloud are analysed. |
