中心药量对燃料的抛散作用

通过燃料抛散过程的高速运动分析系统观测，分析燃料抛散物理过程的不同阶段，阐述了中心药对燃料的抛散作用。研究结果表明，燃料抛散过程可以分为加速运动阶段、减速运动阶段和湍流运动阶段。在一定范围内，燃料抛散的最终云雾半径与FAE装置中心药量无关，它取决于燃料抛散的加速运动阶段和减速运动阶段。在这两个阶段中，燃料分散主要发生在径向。燃料分散的过程与中心药量密切相关。燃料分散的不同阶段应用不同的力学模型来描述。

Dispersal Affection of Center High Explosive Charge to Fuel

According to observation results of the fuel dispersal process with fast kinematics analysis system,the various dispersal stages of fuel are analyzed in this paper.The dispersal affection of center high explosive charge is expounded.The investigation has shown that the fuel dispersal process can be divided into the acceleration stage,the deceleration stage and the onflow stage.In some extension,the end fuel dispersal radius has nothing to do with the canter high explosive charge mass,which is dependent on the acceleration stage and the deceleration stage of the fuel dispersal process.In the two stages the fuel moves along to the direction of radius.The fuel dispersal process is dependent on the center high explosive charge mass closely.The variors stages of the fuel dispersal should be described in the various mechanics model.
