Numerical simulation of pollutants emitted by low-lying sources in the streets

The mathematical modeling results of pollutants spreading within seven parallel streets from low-lying sources are compared in the paper. The calculations were performed using the freeware package Open-Foam and remote console access to the control node computing cluster JSCC RAS Cluster Console, https://unihub.ru/resources/js3console of Web-laboratory Unihub (www.unihub.ru) under the program «University Cluster» (www.unicluster.ru). Motor vehicle emissions in all the streets, that of the chimney on the roof of the first house or both sources simultaneously are considered as sources of pollution. Comparison of simulation results showed that the location of the source has a significant impact on the distribution of gaseous pollutants.
