Packing and flow are two basic modes of granular materials in bulk material handling and processing. Due to the diversity of material properties such as size, shape, density and surface morphology, various unique and interesting phenomena can take place including segregation/stratification, dilatancy, breakage/agglomeration, and more solid- and fluid-like characteristics. Packing and flow of granular materials has been a research focus for many years, with major aims in addressing a range of fundamentals as above in granular packing and flow and also tackling practical problems encountered in material handling and processing. These aims are mainly achieved through discrete- or continuum-based computer models; microscopic analysis of transient flow and force structures; and macroscopic analysis for process design, control and optimisation. This mini-symposium aims to attract researchers to share and discuss the latest modelling techniques and new findings on the packing and flow of granular materials with sizes ranging in a large range from nanometers to millimeters, shapes from regular to irregular, and granular types from nature to industrial processes. The topics suggested for this mini-symposium are including, but not limited to:
• Particle modelling techniques/algorithms
• Discrete element method
• Particle packing
• Compaction and densification
• Particle flow in vessels such as hoppers and mixers
• Pneumatic conveying
• Fluidization
• Mixing and segregation
• Powder spreading in additive manufacturing
• Non-spherical particles
• Screw conveyors
• Cohesive particles
• Filtration
