摘      要：To achieve a synergistic solution for both sustainable waste management and permanent CO_(2) sequestration,CO_(2) mineralization via fly ash particles is an *** on computational fluid dynamics,two specialized reactors for fly ash mineralization were *** reactor designs were strategically tailored to optimize the interactions between fly ash particles and flue gas within the reactor chamber while concurrently facilitating efficient post-reaction-phase *** impinging-type inlet configuration dramatically enhanced the interfacial interaction between the fly ash particles and the gaseous mixture,predominantly composed of CO_(2) and *** design modality lengthens the particle residency and reaction times,substantially augmenting the mineralization efficiency.A rigorous investigation of three operational parameters,that is,flue gas velocity,carrier gas velocity,and particle velocity,revealed their influential roles in gas-particle contact *** a computational investigation,it can be ascertained that the optimal velocity regime for the flue gas was between 20 and 25 m⋅s􀀀***,the carrier gas velocity should be confined to the range of 9-15 m⋅s􀀀*** within these finely tuned parameters engenders a marked enhancement in reactor performance,thereby providing a robust theoretical basis for operational ***,a judicious reactor design was integrated with data-driven parameter optimization.
