Scientific summary :
The main objectives of ASTORIA are to
- propose an alternative to SM and MOM allowing to compute the evolution of the PM population and properties, including morphology and a detailed gaseous chemistry;
- develop a new physically-based DLCA approach for aggregate generation, taking into account physical local conditions along particle trajectories,
- produce radiative properties in the infrared range accounting for soot aggregates morphology.
All these new model developments will be integrated in a CFD code to improve the prediction of emitted PM number and shape in industrial applications, which is the global objective of ASTORIA.
Such developments will also allow to compute radiation in the visible frequency range, in order to reproduce numerically laser-based diagnostics such as static light scattering, line of sight extinction or laser induced incandescence. This will pave the way to a more direct comparison between simulations and experiments for a better understanding and prediction of PM emission.
The improved knowledge and description of soot radiative properties will also increase the accuracy of laser-based diagnostics and climate models.
