摘要
在高能炸药与飞片直接接触的能量转换装置中,炸药爆轰推动飞片,飞片获得动能的同时,其熵值亦增加。本文数值模拟计算了平面一维系统。计算结果给出,适当选取空腔长度和飞片厚度,可实现飞片熵增明显下降的同时,飞片获得的动能不仅不减少还有一定的增加。
The entropic increase of a plate drived by explosive has been researched in one dimension system. Usually. The high explosive is contact with a plate immediately. There is the increase entropy of in the plate resulting from the interaction of a detonation with the plate, while increasing its kinetic energy.The rather idealized problem of detonation products initially at CJ state that expands in one dimension into a void and then accelerates a plate has been analyzed in mathmatical detail. It is believed that the technique described in this report can decrease the enlropic increase and increase some kinetic energy of the plate by choosing the proper length of void and thickness of the plate.
