| 摘 要： | 本文提出一种计算效率高、并改进小扰动理论的二维跨音速定常和非定常流的计算方法——非定常纵向大扰动流速势方程和边界条件的数值解。本方法还考虑了包括边界层位移厚度以及激波-边界层干扰的粘性影响。文中给出了NACA 0012翼型和NLR 7301超临界翼型绕流的算例,计算结果与实验作了比较。

| Abstract: | A new method for calculating of steady and unsteady transonic flows with large longitudinal disturbance and small transverse disturbance is developed.The viscous effects can be considered in present method,including the boundary layer displacement thickness and the shock-boundary layer interaction.The ADI algorithm of monotone switch method and the nonreflecting far field condition are used,the computational efficiency is high. |
