Numerical Simulation of the Atmosphere Pollution After Accident at the "Tolliaty - Odessa" Ammonia Pipe

Abstract

EN: 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.
