From the above simulated evaporation and rehydration process, we can compare them with experimental results. As shown in video files, they both show excellent agreement in the surface profile alteration. The contact angle shrink rate decreased in the end because of viscous fluid. In the rehydration process, the contact angle growing rate is shaper than shrink rate. It rapidly recovered to almost 90 degree in small time period. Both experimental and simulation results showed this phenomenon.
