CFD Simulation of Accumulation and Exhaust Dynamics of Carbon Dioxide in Closed Enclosures

Carbon dioxide is a suffocating gas resulting either from industrial activities or from combustion or explosion. There may also be carbon dioxide deposits under pressure, quartered in porous geological formations. This gas can show slow or violent releases with accumulation at ground level. The presence of this gas in closed or semi-closed spaces can seriously affect the human body and when the concentrations are close to 12% Vol. Death can occur. To establish preventive measures, it is very important to know how carbon dioxide affects the human body as well as how it disperses into the air. Also, in order to establish the necessary measures, it is necessary to know the dispersion dynamics of carbon monoxide both horizontally and vertically. The paper presents the CFD analysis on determining the dynamics of dispersion in the stages of accumulation and evacuation of carbon dioxide in a closed enclosure.
