Numerical Simulation Of Taylor-Couette Flow Between Two Coaxial Rotating Cylinders

关于同轴圆柱之间的旋转流动的Taylor-Couette流是一种典型的旋转流动问题,在润滑理论和工程实践中有广泛的应用。这种流动随雷诺数的增大,在从稳态层流发展到湍流的过程中,表现了一些典型的非线性动力学行为,因此对它的研究具有重要的理论意义和应用价值。利用有限元方法对同轴圆柱间Taylor-Couette流进行数值模拟.轴对称的旋转流动分歧现象被发现,展示了数值模拟结果。

Taylor-Couette flow between two coaxial rotating cylinders is a typical problem of rotating flow, and has extensive application in lubricating theory and engineering. As the Reynolds number increases, this flow loses stability, and displays some behavior of nonlinear dynamics, accordingly, it is very important to study this problem, which values in application. Taylor-Couette flow between two coaxial rotating cylinders was simulated numerically by the finite element method, axisymmetric bifurcation flow between two coaxial rotating cylinders was founded, with numerical results presented.
