Abstract
Aiming at the processes of ignition and powder burning of dispersal-system with central tube bursting-type in the constant volume,the theoretical model was developed,and it was calculated by simulation.The one-dimensional pure gas-phase model was used for the igniter tube with no powder and large length-diameter ratio.The two-dimensional two-phase model was used for the burning process of powder in the combustor.The coupling function of two tubes was established through energy exchange.The calculation program of interior ballistics was programmed by CE/SE method.The calculated results well accord with the test results,and the established model and method are right.The simulation results show that:the ignition process of the igniter tube with no powder and large length-diameter ratio is slow,but the ignition consistency is well.The ignition energy can evenly release to ensure the process of powder burning stably and reliably.关键词
