摘要:
基于软件平台FLUENT6.3,选用标准k-ε湍流模型配合壁面函数法,采用边界层网格计算了近流线型断面雷诺数为1.38×106的三分力系数,并将数值计算结果与高雷诺数风洞试验结果进行了比较,从中选取对三分力系数识别较好的计算网格计算不同雷诺数的三分力系数。结果表明:基于FLUENT6.3的标准k-ε湍流模型配合边界层网格,当近壁面网格控制合理时,能较好地识别近流线型断面雷诺数大于6.0×105的三分力系数; 当雷诺数小于6.0×105时,数值模拟结果不甚理想。
Abstract:
Based on FLUENT6.3, the turbulent model of standard k-ε and equilibrium wall function with boundary layer mesh which was used to solve the flow in the near regions was chosen to research the tri-component force coefficient of streamline-liked section when Reynolds number is 1.38×106. The numerical simulation results were compared with the data obtained from wind tunnel test at high Reynolds number. Meshes which can be identificated preferably were used to solve the tri-component force coefficient under different Reynolds number conditions. The results show that the tri-component force coefficient of streamline-liked section can be identificated preferably by using reasonable control of mesh which is in the near regions when Reynolds number is more than 6.0×105. However, the numerical simulation results calculated by FLUENT6.3 isn't ideal when Reynolds number is less than 6.0×105.
