再生式液体发射药火炮中雾化燃烧过程的模拟

SIMULATION OF JET ATOMIZATION AND COMBUSTION IN REGENERATIVE LIQUID PROPELLANT GUNS

再生式液体发射药火炮（ＲＬＰＧ）内弹道过程最为棘手的问题是对液体（ＬＰ）射流从贮液室喷注到燃烧室，射流破碎形成具有一定尺寸分布的液雾及液滴燃烧这一复杂过程如何进行数学描述。为此提出了一个再生式液体发射药火炮的内弹道改进模型，模型中考虑了膛内气流运动的拉格朗日问题。为此基础上，模拟了液体药雾化燃烧过程。对提出的几种雾化燃烧模型进行了比较，同时与Ｃｏｆｆｅｅ编码计算结果也进行了比较。

For regenerative liquid propellant guns,one of the most difficult problems is how to describe the liquid propellant injection an jet atomization in the mathematic forms.This paper presents an improved interior ballistic model by space mean approach,the problem of Lagrange of gas flow in gun bore is included in the model.Four models of jet atomization and combustion are guien out,and the simulated results are compared with those of Coffeeis code.
