Determination of initial parameters for calculation of emissions from a source with non-stationary emission
One of the specific sources of environmental pollution is vent pipes, characterized by non-stationary characteristics of pollutants emission into the atmosphere. By now, there exist no mathematical models describing such emission sources, and, therefore, there are no models that correctly describe the dispersion of methane in the atmosphere. The paper determines the necessary initial data for describing the dispersion of pollutants from this type of source. The jet diffusion parameters, jet velocity on the ejection axis, and jet trajectory parameters are computed. The effective source is described, and its parameters and components are determined.
