Evaluation of air flow distribution within the design of SMART emission monitoring device

Abstract

Air quality is one of the fundamental parameters in the prospect of a healthy and thriving city environment. With the upcoming tightening of regulations for pollutions in general, it is necessary to provide and access real-time data regarding to the air quality and presence of pollutants within the smart city. The article aims on improving the design of an existing design of an emission monitoring device in previous research. A CFD model was built in Ansys Fluent 2022 R2 consisting of four smart emission sensors, from which the key improvements in terms of air flow characteristics were retrieved from. The article presents a redesign of the flow channels to improve air distribution. Although the pressure loss has increased by 8%, all four sensors show 5,66 m/s air flow with 12 Pa setting of the fan. In conclusion, a physical model of the redesigned geometry must be built and analyzed using PIV methodology with particle flow measurement.
