Abstract
Existing studies on ventilation in train cabins merely considered the mean inlet velocity and ignored the influence of inlet turbulent fluctuation. However, the inlet turbulence can change the airflow characteristics to some extent, thereby affecting the spread of contaminants. This study first comparatively analyses the discrepancy between the URANS and IDDES methods in simulating the internal airflow characteristics, the accuracy of which is provided by the on-site measurement. Moreover, the IDDES method is utilized to investigate the effect of inlet turbulence characteristics on airflow distribution and contaminant dispersion, and the infection risk is also assessed by implementing an improved Wells-Riley probability model. © 2024 18th Conference of the International Society of Indoor Air Quality and Climate, INDOOR AIR 2024 - Conference Program and Proceedings.
