Modeling the Effects of Vegetation on Air Purification Through Computational Fluid Dynamics in Different Neighborhoods of Beijing

Buildings, Год журнала: 2025, Номер 15(7), С. 995 - 995

Опубликована: Март 21, 2025

Previous research has established that vegetation can significantly improve air quality. However, numerical simulations examining the purification effects of on pollutants at neighborhood scale remain limited, particularly regarding different typologies. This study detailed vegetation, buildings, and pollution emissions within neighborhoods by combining high-resolution imagery with field surveys. Then, a computational fluid dynamics model—validated through monitoring—was used to design two scenarios simulate evaluate air-purifying in typical Beijing neighborhoods. The simulation results were also well validated trial-and-error method compared computation absorption coefficients. Findings indicated Dashilar Traditional Hutong Community, contributed reductions 2.39% PM2.5 3.35% CO, whereas east campus University Technology Pingleyuan, more substantial, reaching 10.07% for 8.21% CO. showed size configuration green patches directly influence efficiency, consolidated areas outperforming scattered particle deposition. Additionally, extensive near high-rise buildings may not yield intended benefits. These findings provide robust scientific basis sustainable urban planning practices aimed enhancing

Road intersection analysis: integrating image processing into digital twin technologies

Опубликована: Июнь 20, 2024

We present a real-time system for vehicle detection and classification in road intersections, incorporating image processing techniques. This estimates the traffic flow at specific point, as it is capable of recognizing trajectories different vehicles an intersection, inferring whether they leave or enter city. It designed to be integrated into high-fidelity digital twin, aiding estimating environmental pollutants. Since Computational Fluid Dynamics (CFD) use estimators like average aggregate measurements, we more accurate methods estimate pollution. The implications our study are significant urban planning management. allows immediate decisions informs long-term infrastructure by providing deep understanding intersection dynamics. Our research offers comprehensive perspective on analysis, introducing data-driven management strategies efficient mobility. code developed this purpose can found \https://github.com/capo-urjc/TrackingSORT
