| 摘 要： | 本文构造了轴向大扰动,径向小扰动轴对称速势方程的AF-2分解格式,计算了IC型皮托管式进气道的跨音速内外流场,并对这种分解格式进行了线化的稳定性分析。分析表明:AF-2方法的稳定性优于SLOR方法,其收敛速度至少比SLOR方法快10倍。

| Abstract: | An AF-2 scheme of the axisymmetric small transverse potential equation is formulated and applied in solving external and internal transonic flow about an IC inlet. A linearized analysis of stability for AF-2 scheme is carried out. Analysis shows that the stability of AF-2 is better than SLOR, and the speed of convergence of AF-2 is at least ten times than that of SLOR. |
