摘要

研究了受上游均匀气流作用的方柱体的特性。本研究使用商用CFD软件FLUENT 6.2.16，采用适合层流的本构关系模拟时间分辨流场。利用流动诱导升力系数的变化估计了2000-8000雷诺数范围内的脱落频率和由此产生的平均结构振动。将极限环振荡幅值的仿真结果与已有的实验数据进行了比较。

Numerical simulation of flow past a square cylinder

A study of the behavior of a square cylinder subjected to an upstream uniform air flow is presented. The present investigation uses commercial CFD software FLUENT 6.2.16 to simulate time-resolved flow field using constitutive relationships suitable for laminar flows. Variation of flow induced lift force coefficient is used to estimate shedding frequency and resultant mean structural vibration for the Reynolds number range of 2000-8000. Simulation results in terms of limit cycle oscillation amplitude are compared with pre-existing experimental data.
