| Outline of Final Research Achievements |
In this study, PM aggregation technique was attempted by water vapor addition and condensation. PM exhausted from a benzene laminar diffusion flame formed by a pool combustion system was used as test sample. Mass concentrations of dry up composition and condensed water in water condensed PM were measured by filter sampling method. Size distributions of water condensed PM and non treated PM were also measured by a Low Pressure Impactor. PM diameter (DP) corresponding to a peak mass concentration was around 200nm. Mass concentration of water condensed PM at DP > 200nm was higher than that of non treated PM. Then, mass concentration of water condensed PM at DP < 200 nm was lower than that of non treated PM. Therefore, it was considered that aggregation PM increased at water vapor addition and condensation.
