Modelling indoor pollutant distribution via passive scalar and virtual box approach

The distribution of PM2.5 around a thermal manikin with realistic female body shape in naturally ventilated room has been modelled. health risk (HR) due to inhalation the quantified by integrating pollutants mass flux over boundaries virtual box mannequin’s head (the breathing zone). By same approach HR is evaluated another that surrounds manikins and defines occupied zone. paper focuses on peculiarities creating meshing geometry, as well application user-defined functions (UDF) for defining pollutant source within using Ansys Fluent modelling package.
