Abstract

The vehicle exhaust gas concentration field in the atmosphere of a city block is described by means of solving the system of Euler’s partial differential equations (those of continuity, motion, energy, and state) with the corresponding boundary conditions. The numerical solution is obtained by Davydov’s large particle method. The numerical experiment made it possible to determine the distributions of the main gasdynamic parameters of the gas-air mixture flow and the distribution of the concentration of carbon monoxide entering in the composition of the exhaust gases throughout a three-dimensional domain of complicated shape.
