Numerical Simulation of Indoor Air Pollution and Atmosphere Pollution for Regions Having Complex Topography
In Ukraine, to predict the area of chemical pollution after accidents with toxic substances standard model which is adopted by Government is used. This is the empirical model which possibilities are very restricted. This paper presents numerical models to simulate the flow field and pollutant concentrations in the regions with complex topography. The hydrodynamic model of inviscid flow is used to predict the velocity field over complex terrain and that is the reason of main advantage of these models, because of they do not consume much of computing time. The models can be used for express (quickly ) air quality modeling for cases of air pollution after accidents when there is lack of initial information about meteorological parameters, mass of ejection, etc.
