| 摘 要： | 本文采用一种拟坐标变换掺混方法,计算任意外形机翼的三维边界层流动,亦适用于边界层外流为位流或非位流情况。对C-5A机翼的计算结果表明,该方法具有同微分方法可以比拟的计算精度。并分析了在亚音速情况下粘性对机翼升力和力矩的干扰影响。

| Abstract: | In this paper an entrainment method for 3-D compressible turbulent boundary layer on arbitrary wings is presented. The method can be applied to cases of boundary layer with potential or non-potential external flow fields. The calculating results of this method for the C-5A aircraft wing are fairly close to that of implicit finite-difference method using Cebecis algebraic turbulent model. An example of viscosity effect on the wing lift and the aerodynamic focus location in a subson-ic Mach number using this method is presented also in the paper. |
