三维不可压缩边界层分离流的反解法

INVERSE MODE OF CALCULATION OF THREE-DIMENSIONAL INCOMPRESSIBLE SEPARATED FLOWS IN BOUNDARY LAYER

本文提出了计算具有分离区的三维层流和湍流边界层的一种反解法。计算中采用了半正交曲线坐标系和涡粘性各向异性湍流模型。数值分析中采用了变换域技术和 Keller分块差分格式。用本文方法计算了一个三维边界层分离流实例,计算结果同实验数据吻合得很好。

In this paper an inverse mode of calculation of separated flows in the three-dimensional incompressible boundary layer is presented. The curvilinear semiorthogonal coordinate system and a turbulence model considering the anisotropy of eddy-viscosity are used. And the transformed coordinates and the Keller's box method are applied in the numerical analysis. The calculated results are found in good agreement with experimental data.
