摘要
用Hamilton原理描述爆轰产物粒子运动并最终耗散为热的过程,证明爆轰过程反应区有四组理论解可以达到等容终点,即反应区的多变量解、等温过程解、等压过程解、等容过程解;修正了经典的ZND模型由于忽略输运效应而认为爆轰过程不可能达到等容终点的结论。本文结果与实验结果较为一致。
Experiments prove that in detonation process the isochoric final point is attained,which has been extensively used in explosion engineering.According to the classical detonation theory,the isochoric final point is inaccessible.The Hamilton's principle is applied to describe the complex motion of detonation products' particles and the whole dissipative process;four sets of theoretical solutions,i.e.,the multi-variable solution in the reaction zone,the solution in the isothermal process,the solution in the isobaric process and the solution in the isochoric process,are obtained showing the isochoric final point can be attained.The results reported in this paper are in relatively good agreement with the experimental data.
