Abstract:
We explore the role of partial saturation and accompanying variations in permeability and capillary pressure in capillary rise dynamics into a rigid porous material. Experiments show a deviation from the classical Washburn model dynamics after early times and our aim in this work is to investigate this deviation. We use multiphase mixture theory for modeling to capture a single framework to understand the complex dynamics. We hope to compare the numerically computed results of our model to experimental data and other related literature.
