Influence of granulometry in the Hurst exponent of air liquid interfaces formed during capillary rising in a granular media
We report results concerning the fractal dimension of a air/fluid interface formed during the capillary rising of a fluid into a dense granular media.The system consists in a modified Hele-Shaw Facial Scrub cell filled with grains at different granulometries and confined in a narrow gap between the glass plates.The system is then placed onto a wate
