− | == | + | ==Abstract<!-- Your document should start with a concise and informative title. Titles are often used in information-retrieval systems. Avoid abbreviations and formulae where possible. Capitalize the first word of the title. Provide a maximum of 6 keywords, and avoiding general and plural terms and multiple concepts (avoid, for example, 'and', 'of'). Be sparing with abbreviations: only abbreviations firmly established in the field should be used. These keywords will be used for indexing purposes. An abstract is required for every document; it should succinctly summarize the reason for the work, the main findings, and the conclusions of the study. Abstract is often presented separately from the article, so it must be able to stand alone. For this reason, references and hyperlinks should be avoided. If references are essential, then cite the author(s) and year(s). Also, non-standard or uncommon abbreviations should be avoided, but if essential they must be defined at their first mention in the abstract itself. -->== |

We present a procedure for coupling the

uid and transport equations to model the distribution

of a pollutant in a street canyon, in this case, black carbon (BC). The

uid

ow

is calculated with a stabilized �nite element method using the Quasi-Static Variational

Multiscale (QS-VMS) technique. For the temperature and pollutant transport we use a

semi-Lagrangian procedure, based on the Particle Finite Element Method (PFEM) combined

with an Eulerian method based on a Finite Increment Calculus (FIC) formulation.

Both methods are implemented on the open-source KRATOS Multiphysics platform. The

coupled numerical formulation is applied to the prediction of the transport of BC in a

street canyon, which can be a useful tool to lessen the impact of pollutants on pedestrians.

Two test cases have been studied: a 2D simpli�ed case and a more complex 3D one.

The main goal of this study is to propose a useful tool to study the e�ect of pollution on

pedestrians in a street-level scale. Good comparison with experimental results is obtained.

Keywords: convective transport, convection{di�usion{reaction, transient, �nite element

method, FIC, PFEM, Eulerian, Lagrangian.
