CFD Prediction of Air Quality in the Area between Two City Vehicular Tunnels Considering Moving Cars

Popis výsledku v původním jazyce

Concentration fields of different pollutants that spread outside two road tunnels predicted with a CFD code will be presented. The solution domain represents the city area located between two tunnel outlets - tunnel Strahov and tunnel Mrazovka in Prague.The vicinity of both tunnels is a heavily built up area with tall buildings forming typical street canyons. The CFD modelling predicts the situation after the tunnel Mrazovka will be finished and traffic will increase considerably between both tunnels.Namely, an interest was given to the prediction of dispersion of emissions leaving both tunnel and the area touched by the traffic. For the CFD predictions, a method previously developed for moving vehicles was used. The method uses combination of Eulerian and Lagrangian approaches to moving objects and is capable of modeling different speeds and traffic rates of cars as well as traffic-induced turbulence. Influence of several meteorological parameters was studied, namely wind speed and
