Although structural design offers a promising approach to controlling particle-laden flow, simultaneously reducing deposition and pressure drop while enhancing particle escape efficiency remains a significant challenge, particularly within irregular chambers. Thus, this study focuses on optimizing the trapezoidal chamber geometry to address these conflicting objectives. Specifically, a computational fluid dynamic (CFD)-based surrogate model is developed, achieving high-fidelity prediction across the four-dimensional design space by systematically optimizing its hyperparameters. This enables a multi-objective optimization to map the trade-off landscape, from which a final balanced design is selected using a scenario-based approach. Sensitivity analysis identifies the lower-end width (<em>X<sub>n</sub></em>), horizontal offset (<em>X<sub>m</sub></em>), and trapezoidal height (<em>X<sub>h</sub></em>) as the primary drivers of pressure drop, deposition and escape, respectively. The Pareto-front reveals a vast design space, with specialized configurations reducing particle deposition by up to 78.94%. The selected balanced design concurrently reduces deposition by 19.83% and pressure drop by 15%, while increasing escape efficiency by 9.53%. Lagrangian analysis confirms that the geometry governs particle trajectories by modulating the size and location of recirculation zones. The optimized design also demonstrates robust performance across various inlet velocities and particle sizes.</div></div>","PeriodicalId":7232,"journal":{"name":"Advanced Powder Technology","volume":"37 1","pages":"Article 105126"},"PeriodicalIF":4.2,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145610553","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 results of the study revealed that by reducing the plate spacing from 6.67 mm to 5 mm, the capture efficiency of partial size particles can be increased by 42.18 %. Additionally, increasing the length of the dust collection area by 20 mm can result in a 13.8 % increase.

Although the polarization in ferroelectric under stress can enhance charge separation, this effect is restricted to polar materials. Overcoming this limitation is a key challenge in designing advanced catalyst capable of converting both light and mechanical energy into chemical energy. In this work, oxygen vacancy has been introduced into centrosymatric NaBi(MoO<sub>4</sub>)<sub>2</sub> (NBMO) nanospheres via a facile annealing treatment, which greatly improved the photocatalytic, flexocatalytic and photo-flexocatalytic performance. The composition with optimal oxygen vacancy concentration (NBMO-5) showed remarkable flexo-photocatalytic activity, which achieved 98.7 % RhB degradation within 8 min, outperforming individual flexocatalysis and photocatalysis by 10-fold and 4-fold, respectively. The outstanding performance is attributed to the synergistic effects of oxygen vacancies and flexoelectric potential, which effectively suppress charge recombination and enhance photocatalytic activity. Active species trapping experiment reveals that •OH and h<sup>+</sup> play nearly equally important roles in the flexo-photocatalysis, different from individual photocatalysis and flexocatalysis. Mass spectra analysis indicates that conjugate ring destruction is the dominant pathway during flexo-photocatalytic degradation of RhB by the NBMO-5 catalyst.
