Fig. 6 — (A) A probability distribution is plotted for the DI water daughter droplets that penetrate through the single and double layer of mask A and mask B. For an impacting droplet of size 620 μm, the most probable size of daughter droplets for both masks A and B (single and double layer) falls below 100 μm, which is the regime for possible aerosolization. (B) A comparison of the probability distribution of daughter droplets for impacting DI water droplet and surrogate cough droplet for a single-layer mask B. (C) A probability distribution for daughter droplets at different impact velocities of DI water droplet on a single-layer mask B. (D) A probability distribution obtained for DI water droplet at different impact angles with respect to mask surface on a single-layer mask B.
