Granular materials consisting of discrete particles, are a pervasive material in nature and play a major role in disparate fields of science and technology. To control and manipulate the granular materials in engineering, enriching our understanding of their fundamental characteristics and mechanical behavior is crucial. In this context, one of...
Granular mixing has received less attention than fluid mixing due to the unique properties of granular materials and the complexity of their flow behaviors. Unlike fluid flows, where a continuum perspective accurately captures flow behavior, neither a continuum nor a discrete perspective by itself can describe the global behaviors of...
Segregation of granular materials with different particle properties (e.g.,~size and density) is a ubiquitous phenomenon in nature and industry. In this thesis, different segregation mechanisms are studied in steady granular heap flows. Flow kinematics and segregation in transient granular flows are also explored. ', '\t', 'First, this thesis studies segregation...
