摘要
本文利用现代液雾燃烧理论,详细考虑了再生式液体发射药火炮活塞和弹丸之间多相流区域发生的各种过程,建立了预测其内弹道性能参量及其时空分布的多维多相流模型.模型采用大涡模拟法模拟气相湍流运动,采用连续液滴模型(CDM)描述了多相流区域中液相的行为,对液滴间碰撞效应及液滴与气相湍流间的相互作用也进行了详细考虑.
A Multiphase Multidimensional Model of regenerative liquid propellant gun has beendeveloped to predict the interior ballistic properties and their time—space distributions by consider-ing mainly the multiphase flow area beween the piston and the projectile based on modern sprayCombustion theory.The turbulent Subgrid model and the continuous droplet model are used to dis-cribe the gas turbulence and the liquid droplet behaviors respectively,the detailed considerationsare also put onto the collisions between droplets and the interactions between the droplet and thegas turbulence.
