(a) Simulation of evaporation rate (nL s−1) of a 5 µL sessile droplet as a function of the CA (Θ) based on equation (6)[link] (Marinaro, 2013BB44). The curve of the evaporation rate over the CA is proportional to (1 − H), where H is the humidity. (b) Simulation of the CA change of a 5 µL droplet during evaporation at room temperature. The decrease of CA for t > 2600 s is due to the wetting transition. (c) Simulation of droplet shape change during wetting transition. Note the development of a hollow shape (Marinaro, 2013BB44).
