Abstract

Abstract The method of matched asymptotic expansions has been applied to analyse the asymptotic structure of the incompressible turbulent attachment-line boundary layer at large Reynolds numbers. Inner and outer solutions were obtained that give the ‘wall-unit’ and ‘velocity-defect’ represention of both the spanwise and chordwise velocity profiles. The predictions from the theory agree with experimental and DNS data in the range of fully developed turbulence.

湍流附著线边界层的渐近结构

摘要应用匹配渐近展开方法分析了大雷诺数下不可压缩湍流附著线边界层的渐近结构。得到了给出展向和弦向速度剖面的“壁单元”和“速度缺陷”表示的内部和外部解。在充分发展的湍流范围内，理论预测与实验和DNS数据一致。
