Název v původním jazyce

A dispersion study of CO2 in a room

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 the carbon dioxide (CO2) formation and dispersion in a closed area. A validation of the mathematical model was done on a simple domain with one pollution source, in which values of the CO2 concentration were calculated using CFD and measured. Numerical simulations were carried out by the Reynolds Averaged Navier-Stokes (RANS) approach. The source of pollution was represented by a formation of CO2 creating as a combustion product of the ethanol. Two different methods were used for the calculation of the CO2 formation. The first method adopted the species transport model with reactions and the second method was the non-premix combustion model based on the mixture fraction theory. Both computational methods provided a sufficient agreement of the CO2 concentration with the experimental data.
