| 摘 要： | 为确定液体在毛细管中流动模拟的边界条件，对标准液和树脂在玻璃毛细管中的浸润实验进行了研究，获得了质量随时间增大的浸润实验曲线，并利用CFD软件VOF数值方法对毛细浸润过程进行计算机模拟，获得质量与时间关系的模拟曲线。通过比较模拟曲线与实验曲线，确定了标准液在单毛细管中浸润模拟的边界条件为静态接触角，树脂在单毛细管中浸润模拟的边界条件为动态接触角，为纤维束集合体中的轴向毛细浸润模拟奠定了基础。

| Abstract: | The purpose of this study is to examine capillary impregnation process of glass tube. The penetration liquid weight is recorded as a function of time by electric balance. CFD software is implied to simulate the wicking process and the simulation curves of mass vs. time are obtained. Through comparison of the simulation result with the experiment, the boundary condition is obtained, which lays the foundation for the simulation of axial capillary impregnation process of fiber tows. |
