某防暴枪准两相流内弹道模型及数值模拟

摘要

Based on the modern interior ballistics theory, under the Euler coordinating system, the mathematical model of the quasi-two-phase interior ballistics of a riot gun was established. Under the given assumptions, the basic equations and boundary conditions of the model were given. The Fortran programming language was used to compile the calculation software for the quasi-two-phase interior ballistics. Taking 18.4 mm riot guns as an example, the parameters changing law of a quasi-two-phase flow were obtained for the riot gun. The obtained results provide a solid foundation for the further studies of the operation mechanism of riot weapons.%从近代内弹道学理论入手，在欧拉坐标系下建立某防暴枪内弹道准两相流的数学模型。在给定假设条件下，给出模型的基本方程组及其定解条件。利用Fortran语言编制膛内准两相流场的计算软件，并以18.4 mm某防暴枪为例，获得该防暴枪准两相流各参数的变化规律。该研究可为进一步研究防暴武器工作机理打下坚实的基础。
