Based on all of the work above, this paper studied circular cylinder by the method of large eddy simulation.

在上述工作的基础上，本文对圆柱绕流进行了大涡模拟研究。

At first, to validate the numerical model, the two-dimensional numerical simulation of Vortex-Induced Vibration of a circular cylinder at low Reynolds numbers were carried out and the calculation results were compared with measured data of other researchers'.

应用以上数学模型，本文首先进行了低雷诺数下圆柱涡激振动的二维有限元数值模拟，并与参考文献中的数值模拟结果和物理模型试验结果进行了对比，验证了本文数学模型的正确性。
