Local gas holdup, bubble size distribution, and bubble slip velocity were employed to quantify bubble-induced turbulence, thereby describing its effect on the surface renewal frequency during heat transfer. Without parameter adjustment, the model accurately predicted local heat transfer coefficients under varying superficial gas velocities, pressures, liquid viscosities, and particle concentrations. The simulation results revealed that heat transfer coefficients are positively correlated with bubble-induced turbulence intensity, while in particle-laden systems the variation with particle concentration is mainly governed by particle thermophysical properties. These results highlight that accurate prediction of heat transfer coefficients in slurry bubble columns requires consideration of both hydrodynamics and thermophysical properties. The proposed model provides a unified and reliable method for understanding multiphase heat transfer, offering practical guidance for reactor design, optimization, and scale-up.","PeriodicalId":271,"journal":{"name":"Chemical Engineering Science","volume":"111 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148884577","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}

Current CTFB researches predominantly focus on Geldart A and conventional Geldart B particles. However, our serial studies found that heavy Geldart B particles, denser than quartz sand, exhibit distinct flow characteristics and more uniform radial solid holdup distribution, which enhances gas-solids contact efficiency and benefits carbon capture. Accordingly, this study first determines the onset and cessation of circulating turbulent fluidization for Geldart A, conventional or light Geldart B (B-), and heavy Geldart B (B + ) particles via wavelet analysis method. The recently developed computational mass transfer approach is then employed to comparatively investigate the gas-solids contact efficiency of these three types of particles during carbon capture in CTFBs with different scales. Wavelet analysis method is further applied to process solid holdup fluctuation signals at normalized sampling points to summarize microscopic flow characteristics and correlate them with gas-solids contact efficiency. Simulation results indicate that gas-solids contact efficiency is significantly affected by the apparatus scale-up effect, and the operating window of heavy Geldart B particles is more suitable for large-scale industrial units in terms of both gas velocity and bed dimensions. This work preliminarily elucidates the correlation between microscopic gas–solid flow characteristics and mass transfer performance in CTFBs, highlights the advantages of heavy Geldart B particles in large-scale carbon capture units, and provides theoretical guidance for particle selection in CTFB-based carbon capture processes.","PeriodicalId":271,"journal":{"name":"Chemical Engineering Science","volume":"160 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148884580","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}
