Abstract

For a certain aircraft economy class that has completed the preliminary layout, the diffusion process of particles generated by a passenger coughing under non-full load cabin is analyzed. First, the boundary conditions of particles were defined, including the particle size, number, and sedimentation rate. Secondly, the sparse two-phase flow is used to describe the diffusion process of particles, and the Euler-Lagrangian-Euler mixed model is used to simulate the steady-unsteady-steady diffusion process. Finally, the analysis of the calculation results shows that reducing the longitudinal flow of airflow in the cabin can control the diffusion range of particles and reduce the infection risk for other passengers.
