Abstract:
A three-dimensional mathematical model of the distribution of impurities from a short-term source taking into account meteorological conditions is presented. The model includes the system of equations of hydrothermodynamics describing regional atmospheric processes. The transfer of multicomponent gas impurities is calculated taking into account microphysical processes, precipitation and fog. Initial information for model initialization is aerological information in the form of actual or forecast fields of meteorological parameters and characteristics of sources of impurities. A numerical analysis of the distribution of impurities in the near zone of a cosmodrome from short-term sources such as engines of launch vehicles was performed for various meteorological parameters, including wind in the atmosphere.
Keywords:
three-dimensional numerical model, impurities, distribution, launch vehicle, meteorological parameters, microphysical processes.
