摘要
建立了再生式液体药火炮内弹道过程的多维多相流模型，详细考虑了内弹道过程中多相流区域发生的各种行为，以３７ｍｍ再生式液体药火炮为对象，给出并分析了其内弹道性能参量及其时空分布的数值计算结果。
A multiphase multidimensional model of regenerative liquid propellant gun has been developed to calculate the interior ballistic properties and their time-space distributions by considering mainly the multiphase reactive flow region between the piston and the base of projectile based on modern spray combustion theory.The turbulent subgrid model and the discrete droplet model are used to describe the gas turbulence and the propellant droplet behaviors respectively the detailed considerations are also put into the collisions between propellant droplets and the interactions between the droplets and the gas turbulence.By using a 37 mm test fixture as the calculated target,some numerical results are presented and analysed.
