Special Issue Information

Dear Colleagues,

To provide comprehensive insights into particulate systems and support the development of process industries such as in minerals, chemicals, metallurgy, materials, pharmaceuticals, and energy and environmental sectors, and to advance the green and intelligent transformation and upgrading of related industries, we are organizing a Special Issue named “Advanced Granular Processing Technologies and Applications” in the journal of Applied Sciences. With the theme of "Particle Simulation, Green and Low-Carbon, and Intelligent Manufacturing", this Special Issue invites experts and scholars worldwide to deliver their lastest research results, exploring the  green and low-carbon industrial routes in the context of the "dual carbon" goals, and investigating the cutting-edge technologies in the intelligent control and optimization of complex multiphase flow in mining and metallurgy as well as the underlying challenges in the preparation and application of new materials. We aim for the content of this Special Issue to provide researchers and engineers in various fields, such as mining, metallurgy, materials, and so on, with valuable information and effective references.

Therefore, articles related, but not limited to, the following topics are welcome:

  • Simulation and Modelling of Granular Systems;
  • Green, Low-Carbon, and Intelligent Metallurgy;
  • Optimization of Mineral Processing Systems;
  • Additive Manufacturing, Powder Metallurgy and Intelligent Technologies;
  • Low-Carbon and Advanced Materials Preparation Processes.

Powder bed fusion using a laser beam (PBF-LB) offers a suitable alternative to manufacturing Ti65 with intricate geometries and internal structures in hypersonic aerospace applications. However, issues such as undesirable surface roughness, defect formation, and microstructural inhomogeneity remain critical barriers to its wide application. In this study, a coupled discrete element method–computational fluid dynamics (DEM-CFD) model was utilized to investigate the spreading behavior of Ti65 powder in a multi-layer PBF-LB process. The macro- and microscopic characteristics of the powder beds were systematically analyzed across different layers and regions under various spreading velocities. The results show that the packing density and uniformity of the powder beds in multi-layer PBF-LB of Ti65 powder improves as the number of solidified layers increases. Poor bed quality is observed in the first two layers due to a strong boundary effect, while a stable and denser powder bed emerges from the fourth layer. The presence of a previously solidified region strongly influences its neighboring unsolidified areas, enhancing density in the upstream region and causing looser packing downstream. Additionally, due to the existence of a solidified region, the height of the powder bed progressively decreases along the spreading direction. Full article
