Abstract

Particles suspended in air are often non-spherical shapes, giving rise to shape-dependent complex dynamical processes. Suspended non-spherical particles are associated with a wide array of engineering and scientific scenarios, embodying both their microscopic and macroscopic dynamical behaviors. A comprehensive understanding of the dynamical behaviors of non-spherical particles in air hinges on the accurate identification and description of particle shape, the development of shape-specific models for the forces and torques acting on these particles, and the subsequent micro- and macroscopic phenomena that emerge as a result. This review surveys the latest advancements in the field of non-spherical particles, spanning from shape identification to the characterization of their dynamical properties. An emphasis is placed on establishing a connection between the micro- and macroscopic dynamical behaviors of non-spherical particles. The shape-induced features encompass periodic rotation and preferential orientation, which result in an oscillating migration path and lead to distinctive macroscopic characteristics. The macroscopic features of non-spherical particles are elucidated based on the preceding analysis of forces, torques, and particle-flow interactions. The future perspectives are also discussed in this review.

期刊介绍： The word ‘particuology’ was coined to parallel the discipline for the science and technology of particles. Particuology is an interdisciplinary journal that publishes frontier research articles and critical reviews on the discovery, formulation and engineering of particulate materials, processes and systems. It especially welcomes contributions utilising advanced theoretical, modelling and measurement methods to enable the discovery and creation of new particulate materials, and the manufacturing of functional particulate-based products, such as sensors. Papers are handled by Thematic Editors who oversee contributions from specific subject fields. These fields are classified into: Particle Synthesis and Modification; Particle Characterization and Measurement; Granular Systems and Bulk Solids Technology; Fluidization and Particle-Fluid Systems; Aerosols; and Applications of Particle Technology. Key topics concerning the creation and processing of particulates include: -Modelling and simulation of particle formation, collective behaviour of particles and systems for particle production over a broad spectrum of length scales -Mining of experimental data for particle synthesis and surface properties to facilitate the creation of new materials and processes -Particle design and preparation including controlled response and sensing functionalities in formation, delivery systems and biological systems, etc. -Experimental and computational methods for visualization and analysis of particulate system. These topics are broadly relevant to the production of materials, pharmaceuticals and food, and to the conversion of energy resources to fuels and protection of the environment.
