A numerical study on the relationship between particle dispersion, accumulation, and indoor airflow in different ventilated rooms

This study serves as a basic of the indoor dispersion pollen particles, simulating flow field and discussing behavior particles different diameters in rooms. By comparing vertical velocity components ( w ¯ p $$ {\overline{w}}_{\mathrm{p}} ) mean z-direction component f {w}_{\mathrm{f}} plus terminal settling gravitational V g {V}_{\mathrm{g}} ), differences between values are found to occur mainly at locations close opposite wall inlet. The location is important findings this study, which facilitates improvement simulation method later stage rational design ventilation patterns easily remove from room.
