Abstract

This study aims to compare Eulerian and Lagrangian approaches, specifically focusing on their effectiveness in predicting ventilation rates in single-sided ventilated spaces. This study follows two main steps: (1) elucidating of the characteristics of particle dispersion and deposition in single-sided natural ventilation by indoor/outdoor temperature differences with RANS and LES, and (2) comparing of the Eulerian approach with RANS and Lagrangian approach with LES to predict the particle fate based on particle diameter. The predicted results show that larger particles tend to deposit on floors and indoor surfaces, while smaller particles remain suspended in the air or exhausted to the outdoor. Moreover, the error between Eulerian and Lagrangian approaches was comparatively small in terms of indoor ventilation rate, and the consistency of the two approaches considering surface deposition was confirmed.
