CFD simulation reveals that only adding a secondary air inlet (SA type) at the bottom of the cyclone will create a strong updraft. After adding an air guider, the rotating air enhances the strength of the outer vortex, which is conducive to the particle collection. The experiment results also verify these findings. SA cyclone separator effectively narrows the PSD, but the particle collection efficiency is greatly reduced. In contrast, SAG cyclone separator can decrease the PSD while maintaining a high particle collection efficiency. In addition, it is also found that the collection efficiency of particles decreases with the increase of the opening size of the secondary air inlet, but the SAG cyclone separator is less sensitive to this, making it more controllable in practical applications. To further assess the impact of cyclone modification on coating powder and film properties, the powder coatings with wide PSD and narrow PSD were prepared by original cyclone and SAG cyclone, respectively. It was found that reducing the span of the powder by modifying the cyclone can effectively improve the flowability (angle of repose (AOR), avalanche angle (AVA) and rotating bed expansion rate (RBER)) and film properties (distinctness of image (DOI) and surface flatness) of the particles.

The process of applying four coating layers on high-density uranium dioxide kernel particles results in an increase in particle size and a decrease in density. Most existing coating models at the single-particle scale assume homogeneous coating under thin layer conditions, which makes it difficult to accurately describe the actual evolution process of coated particles preparation. Therefore, this study proposed a particle-binding-type heterogeneous layer (PBT-HL) model combined the binding concept with the CFD-DEM method, which accounts for dynamic changes in the density of coated particles. Then model validation in terms of gas-solid interaction and mass transfer, and coating condition parameter analysis were given at first. The results showed that changes in operational parameters such as the layer density, loading capacity, and inlet gas velocity can affect the spouted fluidization state, further influencing the deposition rate and coating effectiveness. These findings also suggested that the heterogeneous coating model in binding configuration can be further developed to study the anisotropy of single-particle layer thickness quantitatively. In summary, the variable-density PBT-HL model approximates the actual coating layer preparation process more closely, aiding in the acquisition of coating process information and guiding the optimization of coating techniques. The proposed heterogeneous coating model also holds potential for further development to characterize the intra-particle uniformity and the conformality feature of FB-CVD technique in the future.</div></div>","PeriodicalId":401,"journal":{"name":"Particuology","volume":"103 ","pages":"Pages 1-17"},"PeriodicalIF":4.1,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144155119","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
