The purpose of this study is to analyze the unsteady turbulence, deposition, and dispersion characteristics of ultrafine particles of different sizes during the passage of vehicles through a road tunnel. We present a realizable k-ε turbulence model based on a combination of Eulerian passive scalar and dynamic mesh models. A 100-m three-dimensional model of a road tunnel containing four vehicles in a row and 10-m long outlets was established using STAR-CCM+ computational fluid dynamics software. Ultrafine particles derived fro
