摘要
针对密闭爆发器实验过程中压力迅速变化的特点,提出考虑压力因素的热流密度方程,建立密闭爆发器实验中内壁传热的一维半无限大传热模型,推导出实验过程中的传热表达式,并使用该模型对双芳-3(SF-3)、太根(TG)及含黑索今5%(TD-15)和含黑索今30%(TD-30)的三基发射药密闭爆发器实验结果进行了实例验证。结果显示该模型修正出的总热散失与理论值的误差在10%以内,对双芳-3发射药修正得到的燃速压力指数(0.9864)接近该发射药的期望值(1)。
Based on the fast change of pressure in closed bomb tests,a heat flux equation focused on pressure factor was deducted.A one-dimensional semi-infinite model of calculating inwall heat transfer in closed bomb tests was established and the expression of heat transfer was obtained.The model was validated by double base aromatic-3（SF-3）,TEGDN（TG） propellant and triple-base propellant.The results show that the error between corrected whole heat loss and theoretical whole heat loss is less than 10%,and the burning rate pressure index of SF-3 propellant obtained is close to the expected value.
