A mathematical model which can take into account all the scenarios of accidents has been developed. The code AIR-SIM was worked out on the basis of the described difference schemes. This code was used to simulate the atmospheric pollution for different accidents on the territory of the Pavlograd Chemical Plant. In particular, a numerical model was used to predict the atmospheric pollution in the case of HCN emission from the opening at the roof of the building. During the numerical experiment the dynamic of the toxic dose in each room was determined for each case study. It was established that the hitting zone will be about 6 km. © Springer Science+Business Media Dordrecht 2013.

The results of numerical simulation of environment pollution after accident at the ammonia pipe are presented in this paper. The problem was solved for two different scenarios. Firstly only the ammonia ejection into the atmosphere was considered. 3D equation of pollutant dispersion (k - gradient model) and model of potential flow were used to simulate the process of air pollution. At the second step the problems of river Dnepr pollution and evaporation of ammonia from the water surface were considered. The developed numerical models and the code were used to calculate the scale of the air and water pollution. The code was used to calculate the toxic gas penetration into the dwellings of the settlements which are situated near the ammonia pipe. It allowed obtaining the information about the possibility of safety people evacuation. © Springer Science+Business Media Dordrecht 2014.
