摘要

基于有限体积法和Roe离散格式进行了数值计算,分析了不同马赫数和攻角下二维全尺寸飞行器的流场,模拟了发动机内部氢/空气燃料的燃烧反应。计算结果表明:设计马赫数条件下,通过采用三级楔形体(压缩角度8°/6°/7°)对气流进行压缩,能保证进气道有足够的气流捕获量,经过压缩后的高压气体与氢燃料充分混合反应,发动机能以良好的状态工作。

Abstract

In this paper, the 2-D ful-scale flow field, in different mach number and attack angel, was analyz while considered the hydrogen/ air reaction based on the finite volume method and Roe' form. Simulation results show that the engine perform well when using the optimized geometric parameter (8°/6°/7°) in design situation, there were enough pressure and mass of air to make the engine be in best condition.

Key words： hypersonic vehicle; full-scale flow field; chemical reaction; numerical simulation
