Abstract

AbstractThis study serves as a basic study of the indoor dispersion of pollen particles, simulating the flow field and discussing the behavior of particles of different diameters in different rooms. By comparing the vertical velocity components of particles () and the mean flow velocity of z‐direction component () plus the terminal settling velocity in a gravitational field (), the differences between values and plus values are found to occur mainly at locations close to the opposite wall of the inlet. The location of the differences between values and plus values is important findings of this study, which facilitates the improvement of the simulation method at a later stage and the rational design of indoor ventilation patterns to easily remove particles from the room.
