(61a) Measurements of Time-Varying Liquid Spatial Distributions in a Shear Cell Using X-Ray Computed Micro-Tomography

Contact spreading is the transfer of liquid via the formation and breakage of liquid bridges that form between particles. There have been few experimental studies accurately quantifying contact spreading as a function of system properties due to the difficulty of non-intrusively imaging dense granular systems. X-ray computed micro tomography (XRCT) is used in the present work to measure the time-varying spatial distribution of liquid in a shear cell geometry. We discuss the experimental system and procedures in addition to experimental results.
