Název v původním jazyce

A dispersion study of CO2 in a closed area

Popis výsledku v původním jazyce

Predictions of air pollution dispersion in an indoor environment are important outputs to control a fresh air ventilation or energy building efficiency. This study deals with numerical simulations of a formation and dispersion of carbon dioxide (CO2) in a closed area. Numerical simulations were carried out by the Reynolds Averaged Navier-Stokes (RANS) approach. A simple domain with one pollution source was used for a validation of the mathematical model, in which values of the CO) concentration were calculated using CFD and measured. The CO) was created as a combustion product of the ethanol. There were used two different methods for the calculation of the CO2 formation. The tirst method adopted the species transport model with reactions and the second method was the non -premix combustion model based on the mixture fraction theory. The third method used in numerical simulations as a constant mass flow inlet of CO). All computational methods provided a sufficient agreement of the CO2 concentration ial the experimental data.
