本文给出了矩形波纹管中科里奥利效应的数值研究结果。诱导的二次流是从涡产生机制的观点来描述的。在通过矩形通道的充分发展的流的离心作用中，随着旋转速率的增加，由科里奥利效应引起的二次流经历了许多有趣的转变，这些转变对输送现象有影响。这项调查的主要目的是描述科里奥利效应的涡量运输和确定的稳定的解决方案的演变，作为相关参数描述其动态变化。在这项研究中，我们发现了一个区域的非唯一的解决方案在一定范围内的雷诺数。我们还发现，滚动细胞的发病与转折点分岔。
The results of a numerical investigation of the Coriolis effect in flows through rotating-rectangular conduits are presented. The secondary flows that are induced are described from the viewpoint of a vorticity-production mechanism. In the centrifugation of fully-developed flows through rectangular passages, as the rate of rotation increases, the secondary flows induced by the Coriolis effect undergo a number of interesting transitions that have an impact on transport phenomena. The main purposes of this investigation are to describe the Coriolis effect in terms of vorticity transport and to determine the evolution of steady solutions as the relevant parameters describing their dynamics are varied. In this study we found a region of nonunique solutions over a range of Reynolds numbers. We also found that the onset of roll cells is associated with a turning point bifurcation.
