| 摘 要： | 本文采用直接模拟蒙特卡罗方法对稀薄气体二维外部柱体绕流问题进行了数值模拟。结果表明:外部绕流问题,在特定情况下会产生激波,激波的产生,不仅与气体的稀薄程度有关,还与来流马赫数有关。而气流与壁面之间的换热,随来流马赫数增加而增加,随气体稀薄程度增加而减小。

| Abstract: | The rarefied gas flow around two-dimensional rectangular was simulated by Direct Simulation Monte Carlo (DSMC) method, using air as working fluid. It was found that the shock wave will appear under some special conditions, and the intensities of the shock wave were related not only to the rarefied content of the gas, but also to the Mach number of the inlet flow. The heat transfer between the gas and wall increased with the increase of inlet Mach number, but it decreased with the increase of the rarefied content of gas. |
