低超声速圆球绕流后体流场的数值模拟

NUMERICAL SIMULATION OF THE AFTERBODY FLOWFIELD OF A SPHERE AT LOW SUPERSONIC SPEED

  • 摘要: 本文根据圆球跨声速自由飞行实验的流谱结构,建立了低超声速圆球分离流动的流动模型,它成功地计算了考虑粘性分离影响的圆球绕流的后体流场。在计算得到的后体流场中,反映流谱特征的分离激波、尾激波、分离界面等,其位置和形状与实验结果吻合很好,因此本文给出了一种能反映真实流动情况的圆球后体流场介。

     

    Abstract: Based on the flow pattern stniccure obtained from free flight experiments, a method of solving the low supersonic, high Revnolds numbers separated flow problem is proposed in this paper by which the inviscid region of the afterbody flowfield of a sphere has been simulated numerically. Flow characteristics, such as separated shock, wake shock, separation line and wake structure, obtained from computation are in good agreement with the experimental results. The detailed flow structure in the after body flowfi...
