一、引言本文更为准确但略欠简洁的题目应该是“带有纵向(即主流方向)平均涡量的湍流”。这里,我们除了讨论被透平机械工程师定义为二次流的带有嵌入纵向旋涡(embeded-vortex)的流动外,还将回顾和总结一般三维边界层(“3D”)和薄剪切层流动的一些最新成果。至于湍流区和名义上非湍流区的互相作用问题,我们暂不予以讨论。 I. INTRODUCTION The more accurate but less concise subject of this article should be “turbulence with an average vorticity in the longitudinal (ie, the dominant) direction.” Here, we will review and summarize the general three-dimensional boundary layer (“3D”) and thin shear in addition to the flow with embedded embeded-vortex, defined by turbine mechanical engineers as secondary flow Some of the latest results of the mobile layer. As for the interaction between turbulence and nominally non-turbulent areas, we will not discuss them for the moment.
