在半径比η = 0.5的实验装置中，对具有反向旋转圆柱的Taylor-Couette系统中的涡进行了数值研究。完整的，时间相关的Navier-Stokes方程求解的有限差分和Galerkin方法相结合。泰勒涡和螺旋涡解的结构，动力学和分叉行为得到阐明。轴向周期边界条件下得到的一些性质与最近的实验结果进行了比较。
Vortices in the Taylor-Couette system with counter-rotating cylinders are investigated numerically in a set up with radius ratio η = 0.5. The full, time dependent Navier-Stokes equations are solved with a combination of a finite difference and a Galerkin method. Structure, dynamics, and bifurcation behavior of Taylor vortices and of spiral vortex solutions are elucidated. Some of their properties obtained for axially periodic boundary conditions are compared with recent experimental results.
