| 摘 要： | 在实验研究超疏水微通道流动特性的基础上，建立了超疏水微通道流动模型，并利用FLUENT软件选择了合适控制方程，进行了数值模拟。对滑移壁面与无滑移壁面速度分布进行了对比分析。模拟得到的滑移速度，无量纲压降与实验值吻合性较好，最大相对误差分不超过15％、20％。分析了无量纲压降随着Re减小的原因是由于滑移效应的减弱，滑移长度的模拟值与实验值吻合较好，相对误差不超过20％，根据流场分析得出滑移长度可以反映滑移效应的大小。

| Abstract: | On the basis of studying water flow characteristics in the super-hydrophobic micro-tube,water flow model in the super-hydrophobic micro-tube was established,then the control equation was selected,and the model was numerically simulated with FLUENT.The velocity distributions on the slip wall and no-slip wall were analyzed.The simulated slip velocity and the dimensionless pressure drop accorded with experimental results well,and the maximum relative errors were less than 15% and 20%,respectively.The reason fo... |
