项目摘要
Exact coherent solutions in sliding Couette flow, pipe flow and plane Poiseuille flow are obtained by a method of homotopy continuation from the exact coherent solution in plane Couette flow. It is found that a mirror-symmetric spatial structure is commonly observed in these flows and plays an important role in transition from laminar flow to turbulence.
利用平面Couette流精确相干解的同伦延拓方法,得到了滑动Couette流、管道流和平面Poiseuille流的精确相干解。研究发现,在这些流动中普遍观察到镜面对称的空间结构,并且在从层流到湍流的转变中发挥着重要作用。
