本文对毛细微槽中流体的轴向流动特性及干涸特性进行了研究,参考自适应理论建立了一维流动模型,与实验结果进行了对比.计算结果表明随着微槽槽宽的增大、槽深的减小,槽内流体的轴向干涸高度呈减小趋势,与实验数据吻合较好,说明计算方法具有一定可靠性.计算模型得到了弯月面曲率半径和液膜厚度沿轴长的变化曲线,为自适应理论做出有效的补充.
In this paper, the axial flow characteristics and drying characteristics of the fluid in capillary microgrooves are studied, and a one-dimensional flow model is established with reference to the adaptive theory and compared with the experimental results.The calculation results show that with the increase of the microgroove width, The depth of the groove decreases and the axial dry-up height of the fluid in the groove decreases, which agrees well with the experimental data, which shows that the calculation method has certain reliability. The calculated radius of curvature of the meniscus and the thickness of the liquid film along the axial length The curve of the adaptive theory to make an effective supplement.
