摘要
采用雷诺方程与k-ε模型对单圆柱绕流进行了紊流数值模拟,分析了圆柱的风动力系数及圆柱周围的流场。圆柱的风力系数呈现高频变化并具有较明显的周期变化,圆柱的存在影响了流场,且在圆柱后存在着回流。
Reynolds equation and the k-ε model is employed to numerical simulation the flow around a single column in turbulent flow,the wind power coefficient and the flow field around the column is analysis.Cylinder wind power coefficient showed a more high-frequency changes and the cycle change is obvious,the presence of column affected flow field around the column,and the reflux is existence after the column.
