| 摘 要： | 本研究以数值模拟法求解非定常二维激波的斜壁问题。计算采用了时间分割法、MAC格式、FCT修正和自适应网格生成技术。文中对不同马赫数M和不同斜角θ_ω三种组合情况进行了计算。结果表明,采用这种方法所预示的反射形态领域与实验结果吻合良好。

| Abstract: | 2-D nonstatiohary oblique shock-wave reflections over compressive wedges in perfect air were investigated using numerical simulation techniques in this paper. In order to analyze the transport phenomena of 2-D oblique shock-wave, the FCT method with the MacCormack explicit scheme instead of the FCT method with the controlled quality was used, for the former is suitable to general coordinate transformation. The results predicted with the finite difference scheme in the paper are in good agreement with the experimental results in references. |
