超声速、高超声速弧形翼气动特性数值研究

Numerical Simulation of WAF's Aerodynamic Characteristics at Supersonic and Hypersonic Speeds

文中在马赫数（2．0～5．5）范围内进行了弧形翼的数值研究．主要分析了弧形翼在零攻角下产生升力的原因，并且研究了弧形翼曲率对升力的影响。采用有限体积法，MUSCL型三阶迎风格式对N—S方程进行求解，对弧形翼绕流进行了数值模拟．取得了较为满意的计算结果。

Numerical study is conducted to investigate wrap-around fin （WAF） at supersonic and hypersonic Mach number（M∞∈[2～5.5]）. This paper analyses the cause of lift of WAF at zero angle of attack, and researches the effects of the curvature of WAF on its lift, Adopting finite volume method, MUSCL type, third order upwind scheme to solve NS equations, numerical simulation is made to calculate supersonic and hypersonic flowfield over WAF geometry, and some good calculating results are achieved.
