From: Computational characterization of inhaled droplet transport to the nasopharynx
Computed trends of inhaled droplet transport to the nasopharynx: (A) Visuals of heat-maps for inspiratory transmission trends in AR1 (top map) and AR2 (bottom map), showing the percentage of droplets of each size undergoing nasopharyngeal deposition (NPD). The droplets are assumed to undergo environmental dehydration before being inhaled; hence the droplet density is 1.3 g/mL. Data for different inhaled airflow rates are arranged along separate rows. Tracked droplet sizes are along the horizontal axis (positioned between the two heat-maps for AR1 and AR2). NPD peaks for droplets sized between 2.5 and 19 \(\upmu \) in AR1 and 2.5 and 15 \(\upmu \) in AR2. (B) The correlation between RANS-based SST k-\(\omega \) and LES results for the higher airflow rates i.e. 30, 55, and 85 L/min; therein the first three frames (bottom-left) are for AR1, the other three frames (bottom-right) correspond to data for AR2. The frames are on an aspect ratio of 0.5; \(\rho \) represents the Pearson’s correlation coefficient. Heat-maps in (A) are generated by post-processing the simulated data on MATLAB R2020a (MathWorks, Natick, Massachusetts; link to software homepage). The correlation plots in (B) are generated on Mathematica 12.0 (Wolfram Research, Champaign, Illinois; link to software homepage).
