The study of air quality calls on knowledge at the crossroads of both air flow and particle physics. Our specialists, whose expertise is put to the test particularly in mobility sectors, offer a series of aeraulic simulation models with particle transport, that enable us to understand the levels of pollution of various kinds, both indoors and outdoors.

dispersion dynamique
Dynamic mapping of the concentration of pollutants in a transient underground space.

Our Expertise

Our approach is based on numerical simulations of air currents incorporating fine particle transport models. These dispersion calculations take into account real wind conditions and can simultaneously involve dynamic phenomena such as the piston effect generated by a train entering a station. The processing and representation of the results are adapted to the phenomena studied and to the needs of the assignment using computer scripts specific to the study**.
