The paper presents computer models which will allow vehicle pollutant concentrations in a closed domain to be defined. Modelling of pollutant dispersion in an indoor environment requires complex 3D computational fluid dynamics models. The problem becomes more complicated when sources of pollutants are moving in space and time. In the case of closed car parks an integral part of the model is the determination...
The paper presents computer models to carry out numerical calculations, which will define vehicle pollutant concentrations. Emphasis was laid on problems of vehicle pollutant emission and dispersion caused by cold start. The finite volume method was used to discrete equations describing the process of pollutant dispersion. In addition, the two-cycle decomposition method was employed to solve the set...
