Here, new designs are proposed to eliminate the local non-ideal vortex patterns in a conventional Stairmand cyclone by inserting a flow divider at the entrance and adjusting the elbow exit orientation. A two-way coupled CFD–DPM approach is employed to analyze the performance of the modified cyclones. Simulation results show that the cyclone with the elbow exit oriented orthogonal to the entrance direction demonstrates better performance in terms of the cut size and sharpness. The installation of the flow divider reduces the vortex eccentricity by approximately 50%. The flow divider increases the gas velocity near the outer wall, allowing the quasi-free vortex in the cyclone’s outer region to become nearly fully developed at the entrance section through the reduction of the local secondary recirculation flows. The optimum flow divider outer wall thickness correlates to the wall shear stress distribution. With the optimum 2 mm outer wall thickness flow divider installed, the separation efficiency for 2 μm particles increases from 56.74% to 77.4%, and the cut size decreases from 1.87 μm to 1.23 μm.</div></div>","PeriodicalId":7232,"journal":{"name":"Advanced Powder Technology","volume":"36 7","pages":"Article 104937"},"PeriodicalIF":4.2,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144123380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To overcome this, this paper proposes a three-layer digital twin (DT) architecture for predicting the bed profile in rotary kiln. The first layer is the modeling layer, which integrates mathematical mechanism models of material motion into a simulation core to generate simulation data of kiln processing. The second layer is the data layer, where material outlet height data is collected and used to iteratively update simulation results, improving prediction accuracy. The third layer is the interaction layer, where a virtual terminal is designed to retrieve and visually present the results. A small-scale rotary kiln test platform is applied to validate proposed DT. Results indicate that the proposed DT architecture can effectively predict granular bed profile in both steady or dynamic states within a very short time.

A combination of numerical and experimental methodologies was utilized, employing the discrete phase model (DPM) and a coupled computational fluid dynamics-discrete element method (CFD-DEM) to simulate particle–fluid interactions within a 90° elbow pipe. The simulations explored how non-spherical particles, shaped with different degrees of corner sharpness, influence erosion rates, particle dynamics, and localized wear patterns. Experimental observations revealed that maximum erosion was concentrated at the outlet region, where the interaction between particle flow dynamics and pipe geometry intensified localized wear. The erosion rates predicted by numerical DPM simulations were overestimated, particularly in the outlet zone, highlighting the model’s limitations in accurately capturing particle interactions. In contrast, a more accurate representation of localized erosion patterns was provided by CFD–DEM simulations, particularly when non-spherical particles were incorporated. It was demonstrated that angular particles with fewer corners caused more concentrated wear due to higher impact forces, whereas particles with more corners distributed forces more evenly, resulting in less severe erosion. Additionally, Higher particle velocities and kinetic energy intensified impact forces, exacerbating wear, while drag and pressure gradient forces shaped particle trajectories, localizing erosion on the elbow’s outer wall. By integrating these findings, the importance of accounting for particle shape and system geometry in erosion prediction models was emphasized. It was established that the CFD–DEM approach, mainly when applied to non-spherical particles, is reliable for predicting wear in complex geometries, providing valuable insights for designing more durable fluid-conveying systems.</div></div>","PeriodicalId":7232,"journal":{"name":"Advanced Powder Technology","volume":"36 7","pages":"Article 104928"},"PeriodicalIF":4.2,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143947316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of so far strategies including combination with carbon materials, cobalt ions-doping, and formation of nanostructure for improving the performance of NiO are proven limited. Therefore, it is reasonable to infer that the acknowledged electrochemical mechanism about NiO exists a deviation from the actual situation. In this work, we try to use a synergistic strategy of carbon coating and cobalt ions-doping to obtain the high performance NiO. The investigation results prove that the low cycling stability of NiO originates from its dissolution–recrystallization behavior instead of the acknowledged mechanism of stress-induced structure collapse. The carbon coating and cobalt ions-doping improve the external electron transfer property of NiO and its intrinsic electrical conductivity respectively, thus promoting its electro-activity. Consequently, the modified NiO achieves a high specific capacity of 460.8C g<sup>−1</sup> at low current density of 2.0 A g<sup>−1</sup> and keeps a high capacity retention of 61.8 % at high current density of 39.3 A g<sup>−1</sup>. On the other hand, the carbon coating suppresses the dissolution–recrystallization behavior of NiO by its physical hindrance effect, leading to the promotion of its cycling stability from < 10,000 to 80,000 cycles. The results in this work demonstrates the key role of carbon coating in significantly boosting the performance of NiO.</div></div>","PeriodicalId":7232,"journal":{"name":"Advanced Powder Technology","volume":"36 7","pages":"Article 104926"},"PeriodicalIF":4.2,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143941676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
