Course unit contents
This course provides fundamental knowledge, theory, and practical insights for researchers addressing the complex challenges associated with particulate materials and powder flowability. The programme bridges the gap between microscopic particle properties and macroscopic flow behavior, essential for optimizing industrial processes involving granular media.
The course is organized into two core modules. The first section examines the key physical properties and characterization methods for particulate materials, including particle morphology, size distribution, apparent density, and porosity. This includes a detailed analysis of solid-solid contact interactions and the definition of cohesion. The second section focuses on the mechanics of solids applied to powders, introducing static and dynamic stress analysis and yield criteria through Mohr-Coulomb models. Students will investigate active and passive stress states and master the Jenike approach for the design of industrial storage units. This integrated approach ensures that doctoral candidates can translate theoretical yield criteria into robust engineering designs, preventing flow-related failures in industrial handling and storage.
Learning goals
The primary objective is to equip PhD students with a deep understanding of powder flowability and the scientific principles governing granular flow. Participants will acquire the skills to measure and interpret flowability data accurately, understanding the practical implications of these parameters in industrial applications. Furthermore, the course aims to develop the capability to apply solid mechanics and stress analysis to the design and troubleshooting of powder storage and handling units.
