研究了超音速钝锥绕流的稳定性和转捩点预报的数值计算方法，首先采用Euler方程求解钝锥绕流基本流场，用所得到的物面压力分布作为粘性边界层的外缘压力分布，给出了基本流场的初值；然后应用反迭代法与边界层渐近匹配的方法求解了钝锥边界层的稳定性方程，得到了钝锥边界层转捩数据，该方法可提高计算精度，节约计算时间。 |

Numerical method for stability analysis and transition prediction for supersonic flow around a blunt cone is investigated. In order to meet the required accuracy of the numerical values in th basal flow field, the result of the flow field is obtained by solving Euler equations where the pressure attribution on the surface of the cone is used as the outer edge pressure attribution of the viscous boundary layer. The Rayleigh inverse-iteration method and boundary layer asymptotic expansion method are used to solve the blunt cone boundary layer stability equations to get reliable boundary layer transition data. This method improves the numerical precision, and saves the computation time. It is also useful for stability analysis of blunt cone supersonic flow. |
