Numerical simulation (CFD code) was used to optimise the design of the ventilation system of a large underground bus terminal complex near Seoul (Korea). The analysis of air flow patterns and parameters such as NOx and CO concentrations (from diesel engines of 19 buses) allowed to suggest and study modifications of design (change in airflow rates and grilles locations). Changes improve indoor air quality as the mean residual life time of contaminated air decreases.
