Abstract

Abstract

A new reaction model was proposed by thinking of the excitation process and slow reaction in the detonation process of insensitive high explosives (IHE). This reaction model can be used in coarse mesh as compared with other reaction model. In the mesh of 50 cells per centimeter, the calculated results of the free velocity of tantalum and aluminum flyers driven by IHE are according with the experiment data. This model was applied to calculate the process of IHE driving LiF. In the mesh of 50 cells pre centimeter. The calculated result of the interface between LiF and IHE is according with the experimental data. When the mesh size is smaller, the error between them is smaller. It indicates that this new model can describe the process of driven flyers by IHE in coarse mesh, and it can be used in practical works.
