| Research Abstract |
In the present study, a numerical simulation of a drying droplet of fine particle suspensions on the substrates with homogeneous or line-shaped patterned wettabilities was performed to investigate the contact line motion of the droplet, particles transport and deposit on the substrate. The simulated contact line motion showed a qualitative agreement with experimental results. In contrast, as for the film formation of particles, the present numerical simulation overestimated the particles transport toward the droplet center caused by the contact line recession, resulting in the formation of the dot-like shaped deposit which is inconsistent with experimental results.
