Key Findings in This Report

• • Computational time per operating condition reduced by 71.4% compared to traditional FLIC-Fluent coupling, enabling rapid multi-condition optimization. • • Maximum relative error of furnace temperature simulation vs. on-site measurements ≤4.10%, outperforming the 9.68% error of the traditional method, ensuring higher predictive accuracy. • • Fully coupled simulation within a single Fluent platform eliminates cross-software boundary errors (previously 5-8%) and manual intervention, improving reliability. • • The method resolves the particle dispersion distortion issue in traditional FLIC models, accurately capturing bed combustion dynamics for multi-source solid waste.
