Abstract

In this study, motion and deposition of various sizes of aerosols in turbulent flow of air inside and outside of two-dimensional buildings with closed and open windows have been investigated, numerically. This simulation was based on FVM solving of RANS equations with k–ε model. Eulerian–Lagrangian method was used to simulate fluid and particles motions, respectively, and one-way coupling between them was considered. Effect of particles size on deposition efficiency has been calculated. The results shown that, the particles deposition outside and inside of the building with domical roof is less than triangular and flat roof buildings.
