Professor Kim Won-jung research team found out the condition
to form water drop over the string
Sogang University Department of Mechanical Engineering professor Kim Won-jung team found out interaction formula to predict what kind of process has to be fulfilled in order for the water drop to be left over the string from the collision process of fluid drops. The research result was published in academic journal related to fluid mechanics called ‘Physics of Fluid’ on April 12.
Professor Kim Won-jung research team carried out an experiment by differing the diameter of water drop and diameter of string and collision speed from each other then filmed the process of water drop landing on the string with high-speed camera, as the result, when the collision speed of water drop slows down, water drop form in the string and exposed a fact that at that time, the contrast of size differences between the diameter of the water drop and diameter of the string are important.
