论文摘要
开发了一个计算流体动力学（CFD）模型，以模拟半月板形成和垂直平行板之间的毛细管流动的动力学。采用任意的拉格朗日 - 欧拉（ALE）方法来预测和重建弯月面的确切形状。该模型用于模拟水的升高和半月板在垂直通道中的演变，其间距值为0.5 mm，0.7 mm和1 mm。通过比较稳态毛细管高度和半月板曲线与分析溶液来确定模型的有效性。开发的模型提出了一种新的方法，用于模拟毛细血管流量，该方法占无法通过分析模型捕获的详细流体动力现象。
A computational fluid dynamics (CFD) model is developed to simulate the dynamics of meniscus formation and capillary flow between vertical parallel plates. The arbitrary Lagrangian-Eulerian (ALE) approach was employed to predict and reconstruct the exact shape of the meniscus. The model was used to simulate the rise of water and the evolution of the meniscus in vertical channels with various spacing values of 0.5 mm, 0.7 mm, and 1 mm. The validity of the model was established by comparing the steady-state capillary height and the meniscus profile with analytical solutions. The developed model presents a novel approach for simulation of capillary flow accounting for the detailed hydrodynamic phenomena that cannot be captured by analytical models.
