Abstract
EN: Diesel locomotives are widely used at Ukrainian railway stations as maneuvering
locomotives. Emissions from these diesel locomotives contain different toxic chemicals. It is
important to understand air contamination patterns which are formed at railway stations.
Understanding of these contamination patterns allows to evaluate the negative impact of diesel
locomotive emissions on environment. To solve this problem it is necessary to use
mathematical models which take into account the most important factors influencing formation
of contamination zones. This paper introduces numerical model which allows to simulate
pollutants dispersion from moving diesel locomotive. Developed numerical model is based on
three dimensional equation of potential flow and three dimensional equation of pollutant
dispersion. The model takes into account pollutants (NO, NO2) chemical transformation. To
solve three dimensional equation of potential flow the implicit difference scheme of splitt ing
was used. To solve three dimensional equation of pollutant dispersion the implicit difference
scheme of splitting was used. Euler method was used to solve numerically equations of
pollutant chemical transformation. Developed numerical model allows to take into account
influence of buildings at the railway station on the contamination zones formation. Developed
model consumes not much computer time. Results of performed numerical experiment are
presented.
