使用谱法对通过方形横截面的弯曲管道的流量进行三维 (3D) 计算。本文的主要关注点是阐明周期解的 3D 结构，这些周期解是通过假设主流方向均匀的二维 (2D) 计算获得的。研究发现，在2D模拟获得周期解的参数区域内，3D数值模拟可以实现行波解。精确的行波解是通过迭代方法从时间演化计算给出的初始猜测获得的。在横截面中观察到的 3D 行波的流动模式与 2D 周期解的流动模式非常相似。
Three-dimensional (3D) calculations of the flow through a curved duct of square cross section are conducted by use of the spectral method. The main concern of this paper is to clarify 3D structures of periodic solutions which have been obtained by two-dimensional (2D) calculations assuming uniformity in the main-flow direction. It is found that traveling-wave solutions are realized by 3D numerical simulations in the parameter region where periodic solutions were obtained by 2D simulations. Exact traveling-wave solutions are obtained by the iteration method from an initial guess given by the time-evolution calculations. The flow patterns of a 3D traveling wave observed in a cross section are very similar to those of 2D periodic solutions.
