    Abstract: 超音速燃燒衝壓引擎是一種有高技術難度的推進系統,其運作的環境通常為空氣密度較稀薄的流場,在這種情況下巨觀的連續流體的假設基礎呈顯薄弱,需改用微觀的粒子流體模型的觀點進行分析,本文使用直接模擬蒙地卡羅法(DSMC),此法是目前較為被廣用於模擬分析粒子運動行為模式的方法。
    Scramjet is a very high-tech difficulty of the propulsion system, it operations of the environment usually as the thinner the air flow field, in this case macro based on the assumption of continuous flow was obviously weak. Hence, we have to discuss flow fluid by microscopic molecular model, this article using direct simulation Monte Carlo (DSMC), this method is more widely used to simulation analysis the particle movement patterns.
    As the Scramjet operating at high Mach number environment, therefore, when the free stream into the flow field still maintained the high momentum at this time how to make the fuel and air can be mixed well in this environment has become an important issue, mixing situation direct affect the quality of combustion, which also will produce the thrust is directly related, this article generated under different shape to do a series of mixing efficiency analysis.
