CFD prediction of air quality in the area between two city road tunnel outlets considering moving cars

pages 132 - +6p, full text

In the contribution, concentration field of different pollutants predicted with a CFD code are presented. The calculations were done with Star-CD 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 [2j. The method has a significant advantage of separating contributions from different sources to a total 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 in the city area located in the vicinity of the upper portal of the Pisarky tunnel in Brno. The comparison of the results based on computer modelling and the values based on the measurements are presented.
