Formation and dispersion of CO2 after combustion in closed area

Popis výsledku v původním jazyce

This study deals with the formation of carbon dioxide (CO2) after combustion process and dispersion in a closed area. The formation and dispersion of CO2 were numerically simulated and validated by experiment. Ethanol (C2H5OH) was chosen as a fuel for the combustion process. Numerical simulations were carried out by using Reynolds averaged Navier–Stokes (RANS) approach with k-ε and k-ω turbulent models. The combustion process was simulated using two methods. Species transport with chemical reactions was the first method, and the second method was the nonpremix combustion model based on the mixture fraction theory. There were done some sensitivity studies on the influence of the time step size and a resolution of computational grid. Results from numerical simulations were validated by experimental measurements, where the CO2 concentration was measured by the non-dispersive infrared (NDIR) sensor at four points.
