FIG. 7. — Numerical simulations of a breath-generated aerosol plume in a turbulent boundary layer using a large eddy simulation (LES). (a) The transit of breath aerosol puffs is represented by contours of $C / C_{o} = 0.01$ , (b) Mean concentration contours for a light plume (warmer than ambient temperature of $0^{°}$ C), (c) heavier plume (colder than ambient temperature of $42^{°}$ C), and (d) the mean concentration along the streamwise direction at 1.5 m above ground (in meters). The best-fit power laws beyond the near-field region are also shown. The temperature of the exhaled breath was assumed to be $37^{°}$ C. Reproduced with permission from R. Mittal, C. Meneveau, and W.
