The research on the relationship between vortex evolution and diffusion of aerosol in human upper respiratory tract can deepen understanding of the characteristics of the particle deposition pattern in human upper respiratory tract and plays a very important role in analyzing the transition of aerosol in human upper respiratory tract. Large eddy simulation and an efficient Lagrangian particle tracking module were used to simulate relationship between vortex evolution and diffusion of aerosol in mouth-throat model in the conditions of the low intensive respiratory, and the vortex evolution and the mechanism of aerosol transition in human mouth-throat model were discussed. The results show that the diffusion of small aerosol particles follow the vortex structure very closely; the capabilities of the vortex for carrying aerosol particle increase with increase in vorticity, which can affect the diffuseness and deposition of the particles.
