Effect of channel at edge of cup to prevent liquid adhesion. Japan Society of Mechanical Engineers, 2017, vol.83.856
(abstract) Based on experimental observation of liquid dripping, a method to prevent liquid adhesion at the wall of cup was proposed in
this paper. When water or sauce etc. is poured from edge of a cup or a pot, the liquid adheres to the wall of cup, which often
makes a table or clothes dirty. To clarify the above annoying problem, the flow dripping from the cup, whose edge was
shaped to have various thin channels, was observed by using high speed camera. We found the water adhesion on cupfs wall
reduced when the channels were located at the outside of edge of the cup.
