Improved guidelines of indoor airborne transmission taking into account departure from the well-mixed assumption

We use large eddy simulations with the Euler-Lagrange point-particle approach to assess appropriateness of well-mixed theory in predicting indoor risk contagion. A novel `statistical overloading' technique allows us analyze infinitely many scenarios, only one data-rich simulation. The figure shows droplet nuclei (left half room; see color map for radius `r') and an iso-surface velocity magnitude (in yellow). inset (bottom right) expiratory events that can be analyzed.
