摘要

环境污染和空气质量是智慧城市和国家法规领域日益重要的话题。本文的目的是介绍用于家庭非工业加热器具的排放监测系统的设计进展。本文分析了在小型热源上实验测试的监测系统设计中可能存在的改进机会。利用Ansys Fluent软件2022 R2中的计算流体动力学(Computational Fluid Dynamics)对几何修改、传感器位置和方向进行了评估，包括空气和CO/CO 2弥散模型。最后的几何形状引入了一个流线型漏斗和一个分离元件，它在传感器之间均匀地分布气流。结果表明，随着下游速度标准差从±0.693 m/s提高到±0.297 m/s，气流更加均匀。总之，这些结果有助于减少空气污染。

Improvement of Emission Monitoring System Accuracy in Aims of Increasing Air Quality of Smart City

Abstract Environmental pollution and air quality are increasingly important topics within the areas of Smart City and state regulations. The aim of the article is to present the progress in the design of the emission monitoring system intended for use in non-industry heating appliances in households. The article analyses potential opportunities in aims of improving the design of a monitoring system that was experimentally tested on small heat source. Geometry modifications, sensor placements and orientation were evaluated using Computational Fluid Dynamics in Ansys Fluent software 2022 R2 including both air and CO/CO 2 dispersion models. The final geometry introduced a streamlined funnel along with a separation element, which distributed the air flow evenly between the sensors. The results showed more uniform air flow as the standard deviation of downstream velocity improved from ± 0,693 m/s to ± 0,297 m/s. In conclusion, these outcomes assist in the reduction of air pollution.

期刊介绍： Mobile Networks and Applications'' technical scope covers mobility solutions that provide communication technologies and mobile services, which enables users to access resources and share information freely, anytime anywhere. The emerging symbiosis of wireless communication, the ever more powerful mobile devices, with the back-end resources of the cloud, making the user fully location independent. The journal addresses the convergence of mobility, computing and information organization, services and management. In approving Special Issues, the Journal places an equal emphasis on the various areas of nomadic computing, data management, related software and hardware technologies, and mobile user services, alongside more `classical'' topics in wireless and mobile networking. The journal documents practical and theoretical results which make a fundamental contribution.
