Abstract
The paper introduces a new versatile silo model that was especially designed for in situ X-ray tomography studies of silo discharge for various flow conditions, namely concentric and eccentric. The presented work focuses on organic granular materials where low fraction of short-grain white rice is mixed with spheroidal sorghum particles. The high-quality tomography images combined with adequate image processing strategy allows to unambiguously analyze individual grains dynamic behavior during silo discharge. The quantitative image analysis also reveals granular compaction rates in different zones of the funnel flow, which are in agreement with the literature. The proposed experimental methodology is proven to be solid enough to investigate in more details dynamic phenomena during silo discharge. It can also serve as a strong baseline for numerical calibration and predications.
