Figure 4. Contour plot of the vapor concentration distribution above a droplet of radius R = 1 mm and height h0 = 0.364 mm. Parameters used in the FEM method are vapor diffusivity D = 26.1 mm2/s, relative humidity H = 0.40 and saturated vapor concentration on the droplet surface cv = 2.32 × 10−8 g/mm3. Gray bars represent the vapor concentration in g/mm3. Reprinted with permission from [31]. Copyright (2020) the American Chemical Society.
