Original language description

In the contribution, concentration field of different pollutants predicted with a CFD code will be presented. The calculations are done with StarCD code into which a special subroutine for moving vehicles is integrated. This subroutine is based on 3-D Eulerian-Lagrangian approach to moving objects and is capable of taking into account the traffic induced flow rate and turbulence (see Jicha et al., 2000). The method has a significant advantage of separating contributions from different sources to a totall concentration field of different pollutants. In such a way we are able to clearly determine what is the impact of tunnel outlets, line sources from vehicles moving along roads and what is the background. The method has been applied to prediction of concentration field of CO and NOx in the city area located between two tunnel outlets - tunnel Strahov and tunnel Mrazovka in Prague. The modeled area has dimensions approximately 600m x 600m and is situated between two hills. Both tunnel ou
