Performance comparison of four aerosol particle transport models used in indoor air environment

Presents four transport models of aerosol particles, including Lagrangian particle tracking model (LPTM), ordinary drift-flux model (ODFM), modified drift-flux model (MDFM) and passive scalar species transport model (PSSTM). Simulates the dynamic distributions of particles with 1 to 5 μm diameter by four aerosol particle transport models in a two-zone experimental chamber, respectively, and compares the simulation results with the measured data. The results show that the four particle transport models can generally obtain nearly similar results consistent with the measured ones. The overhead in the computer memory resources and the pure computation time are quite distinct when applying the four particle models.
