Abstract:
To describe the concentration fields of automobiles exhaust gases in the city atmospheric air, the system of differential equations of continuity, motion, energy, state and concentration with appropriate boundary conditions is used. The numerical solution is based on the large-particle method. The computational experiment allows us to determine over a complex spatial area the distribution of the main gas-dynamic characteristics of a gas-air mixture flow and concentration distribution of the gas that similar to the carbon monoxide and is a common constituent of the exhaust gas.
Keywords:gas dynamics, stream of gas-air mixture, gas impurity concentration, pollution over urban territories, stochastic process of Poisson’s type.
