Abstract

The transport and distribution of aerosol particles from outdoor environment to indoor environment were experimentally studied. A scaled two-dimensional experimental setup was built to simulate the indoor and outdoor environment, the time-dependent concentration of the particles from outdoor with a diameter distribution of 0.3-10.0 μm was measured inside the chamber to illustrate the influence of the particle diameter on the distribution and dispersion of the particles. The results show that the difference of the particle concentration is observed for different ventilation situations, because the flow field configuration effectively influences the particle dispersion at certain position in indoor environment. The particle diameter also influences the concentration distribution and the dispersion of the particles. The larger the particles, the lower the dispersion efficiency is. When the inflow air velocity is high, the difference of the particle concentration distribution among the particles with different diameters is very little. When there is no inflow gas at the inlets, the difference reaches the highest level.
