湍流强度（turbulent intensity）：I=0.16Re^(-1/8)；其中，雷诺数：Re=vdρ/η；v-平均速度；P2=P1-1/2ρv^2；P1-进口压力；P2=出口压力；d-口径；ρ-介质密度；η——介质动力粘度系数；流体力学书上都有；或者，在网上下载个湍流强度计算的小程序，输入参数即可；5%，我在混合器中输入5%...
设置Turbulence Specification Method为Intensity and Hydraulic Diameter,用强度和水力直径设置湍流: 设置Turbulent Intensity (%)为10 %,湍流强度10%, 设置Hydraulic Diameter (m)为0.0127 m,水力直径用圆管直径给定即可; 设置Reynolds-Stress Specification Method为K or Turbulent Intensity。 OK关闭进口速度设置对话框。

如果来流是充分发展的，湍流强度就可能较高了。至于计算公式，fluent说明书上虽然后有，但除非你的模拟精度要求很高，不然就没有这个必要，说明书上讲，只要保证边界值不至于太不符合物理规律，以至于影响到计算结果或是收敛情况。所以你只要大致给个就可以了。
