• 中文摘要： 本文以實驗及理論探討毛細吸引裝置中粒子沈降對溼潤前緣動態行為之影響。基於以往工作所發展出包含粒子沈降效應之動態模型可適當地描述實驗結果,而影響效果顯著之區域亦加以標示。本研究發現對於小至中尺寸之濾紙而言粒子沈降可予以忽略,但對大尺寸濾紙而言,粒子沈降為影響系統最重要之因素。
• 英文摘要： Effects of particle sedimentation on the wet front dynamic behaviour of capillary suction apparatus (CSA) tests are investigated experimentally and theoretically. A dynamic model incorporating particle sedimentation effect, which is an extension of our previous approach, is solved numerically with zone settling velocity and average specific resistance as model input data. Numerical calculations agree fairly with experiments. The regions of significance are also mapped. In most tests with filter papers of small to medium sizes, particle sedimentation effect can be safely neglected. However, when the filter paper size is large, particle sedimentation might be the most influential factor in determining the CSA dynamics.
