Numerical simulation of CO2 dispersion in an auditorium

This paper presents the simulation of the air flow field in an auditorium. A CFD code is used for the numerical simulation of CO2 dispersion caused by breathing of people present in the closed space. Two different ventilation systems, air induction and abduction flow rate, the number of the people, as well as the lighting equipment are taken into account. The geometry considered is three-dimensional and the turbulence phenomena are also accounted for.
