通过对液体滴落现象的实验观察，提出了一种防止杯壁液体粘附的方法。当水或酱料等从杯或锅的边缘倒出时，液体会粘附在杯壁上，这经常会弄脏桌子或衣服。为了解决这一问题，利用高速摄影机对从杯形容器中滴落的流体进行了观察。研究发现，当通道位于杯壁边缘外侧时，水在杯壁上的粘附力降低。
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 cup’s wall reduced when the channels were located at the outside of edge of the cup.
