Abstract
The primary of this study is to evaluate the characteristics of airflow organization and particle deposition in blocked ducts with various subgrid models. Five popular sublattice models are chosen to conduct this and the LES method is utilized to simulate the flow field and particle deposition properties of the duct. The results demonstrate that the features of the flow field varied amongst the different sub-grid models. The Smagorinsky and WALE models provide comparable findings, with only one pair of separated vortices in the leeward region. With small separated vortices and a small vortex structure near the wall in the leeward region, the WALES model, the WALES-Omega model, and the KET model are more informative. Simultaneously, a large number of particle groups with particle sizes ranging from 1nm to 50μm were selected for particle phase analysis. It was discovered that the deposition velocity of ultrafine particles below 1μm steadily reduced as particle size grew, whereas the deposition velocity of particles larger than 1μm rose as particle size increased.
