摘要/Abstract

摘要： 采用三维非定常化学反应控制方程组对驻定在带攻角高速飞行弹丸上的斜爆轰波流场进行了数值模拟。对流项和化学反应项采用时间分裂法,分别用TVD格式和基元反应模型进行处理。计算结果表明三维数值模拟可以更准确的描述弹丸飞行攻角对爆轰波的形成及结构的影响,是进一步研究超驱爆轰推进技术的重要手段。

Abstract: The three-dimensional(3D) Euler equations are applied to the study of numerical simulation of chemical non-equilibrium oblique detonation wave standing on an accelerating projectile with attack angle.Using time splitted algorithm,the convection term is solved with TVD method and the chemical reaction is dealt with elementary reaction model.The results indicate that the attack angle can largely affect the configuration and structure of detonation wave.
