Abstract
The objective of this paper is to study the air flow and the carbon monoxide dispersion coming from vehicles within an idealized street canyon. The mathematical modelling used is based on the numerical solution of the mass, momentum and chemical species equations using the RANS methodology, which is used to model the turbulent flow. The finite volume method is applied through the commercial software Ansys Fluent 22.0. The results obtained were verified and compared with experimental results available in the specialized literature, which will determine the accuracy of the numerical model used and contribute to understand the carbon monoxide behavior inside an street canyon.
