Numerical simulation pollutants transfer in industrial rooms after accidents

The numerical models proposed can be used to predict air pollution in industrial rooms for different type of ejections (accident spillage, short time ejections, etc) permitting to take into account both the equipment situation in the room and in- and out openings of ventilation. The numerical models permit to calculate the process of toxic gas neutralization from steady and mobile sprinklers. Numerical integration of model equations is carried out using implicit change-triangle difference schemes, A.A. Samarski’s method and Libmann’s method. The results of numerical experiments carried out to investigate the processes of air pollution in industrial rooms for the different type of accidents and different ways of toxic gas concentration reduction are presented.
