| Outline of Final Research Achievements |
From our experimental observation of liquid dripping, a method to prevent liquid adhesion at the wall of cup was invented. To clarify this annoying problem, the edge figured with thin channels was observed, and we found the water adhesion on cup's wall reduced when the channels were located at the outside of edge of the cup.
The numerical simulation of dripping water from the edge of the cup was carried out using the Explicit Moving Particle Simulation (MPS) method. Introducing the wetness model on the wall, the simulation result was good agreement with that of experiment in expressing water adhesion on the wall of cup.
