高精度迎风格式的射弹粘性绕流场数值模拟

APPLICATIONS OF HIGHER-ORDER UPWIND SCHEME FOR VISCOUS FLOW OF PROJECTILES

应用四阶的MUSCLTVD格式 ,求解雷诺平均的N S方程 ,对超音速射流与弹体绕流流场和弧形翼的空气动力特性进行了数值模拟研究 ,计算结果与实验对比表明 。

In this paper, the research about this interaction flows was completed with fourth order MUSCL TVD scheme to solve the reynolds-averaged N-S equations. Thus interaction flowfield between flow around the body and base jet was studied, and aerodynamics characteristic of projectile with WAF was computed, and data were compared with experiments. These results revealed that this technique is capable of providing visualizations of flow fields with high resolution.
