| 摘 要： | 将改进的Jameson格式应用到多翼导弹的三维流场计算中,并使用分区技术和三维椭圆微分方程数值网格生成技术以精确模拟此复杂构形的复杂流态,计算结果与美国导弹标模的实验吻合很好.一系列攻角下导弹三维流场的数值模拟表明,修正Jameson中心差分格式能够适用于复杂外形、复杂流态、亚/跨/超/高超音速的流场计算,而且精度和分辨率都比较高,结果可信.

| Abstract: | The applications of modified Jameson's scheme to the complex flow around the missiles with canards and tails, result in good agreement between computations and experiment data of the standard missile model of U.S.A.. In computations, the latest modifications of Jameson's scheme are adopted to extend applications of the scheme to high supersonic and high Reynolds number flows. The multi-zone technique and 3-D elliptic grid generation method are also employed to precisely simulate the flows. |
