분자동역학을 이용한 물 액적의 유착 현상에 대한 연구

In the present study, the behaviors of nano water droplets were investigated using molecular dynamics simulation. In general, separated nano water droplets merge each other because of interactive force by Lennard-Jones potential and Couloumb potential. We focus on understanding the merging mechanisms of nano droplets. The calculations were extended to droplets having ratio of radii between 0.4 and 1.0 and initial distance between 2A and 8A , respectively. Then, we observed the shape of droplets and time spent on merging. The time spent on merging rises linearly with according to the increasing of droplet ratio as we expected. Also, the time spent on merging is getting increases with according to the increasing initial distance, however, when the initial distance is more than 8A merging time is observed to be perturbed.
