摘要
利用计算流体力学软件Fluent对均匀来流绕固定圆柱的流动情况进行了数值模拟,考察和研究了气流绕过圆柱时的边界层的形成以及旋涡的形成及脱落过程,利用粒子图像测试(PIV)技术对绕流情况进行了实验研究。通过数值模拟结果与PIV实验结果的定性和定量分析比较,证明Fluent软件的模拟结果具有相当的准确性,能够准确的预测流体的流动特性。
The uniformflow flowing around a circular cylinder is simulated by the application of the hydromechanics software Fluent. The formation of the boundary layer, the formation and breaking off of vortex are studied. The experiment research on the flowing over a circular cylinder is based on the particle image velocimetry (PIV). Comparing with the result of PIV qualitative and quantitative analysis, the simulation result of the Fluent software is quite accurate, and can forecast the flowing characteristic of fluid.
