Abstract


Engaging in industrial activities necessitates the utilization, manipulation, or inadvertent occurrence of hazardous compounds, such as carbon monoxide. The occurrence of this gas in enclosed or partially enclosed areas can have a significant impact on the human body, and at elevated levels, it can result in fatality. Understanding the impact of carbon monoxide on the human body and its dispersion in the atmosphere is crucial for developing effective preventive strategies. This paper presents experiments and CFD (Computational Fluid Dynamics) modeling to establish the dynamics of carbon monoxide dispersion during the accumulation and evacuation stages in a closed enclosure. Toxic and explosive gas - carbon monoxide, discharged within a confined space, there was a display of relatively uniform accumulation phenomenon in the enclosure. The design of the kind of carbon monoxide spreading in the closed area showed a dilution focused on phenomena towards the suction mouths. Carbon monoxide has a high dilution capacity due to the rapid decrease in gas concentrations during the exhaust process.
