Study on the relationship between indoor airflow and particle movement under different air change rate using CFD-Lagrangian simulation

抄録

This paper discusses the relationship between indoor airflow and particle movement with different air changes per hour (ACH). CFD simulations with the Lagrangian method were used for simulation. We found that the different ACH affected the difference between indoor flow and particles considering settling velocity. And the z-component of velocity difference between the Lagrangian result and terminal velocity became significant with the increase of ACH.
