IN recent years, the characteristic behavior of nanoscale liquid thread has drawn much attention because of its scientific interest and industrial applications. Since the experimental investigation of liquid thread properties and its stability is extremely formidable, most studies rely heavily on the theoretical or numerical approach. MD simulation is one of the useful methods to investigate interfacial phenomena and stability of nanoscale liquid thread since it can monitor dynamic motion of each molecule in the system. It can provide detailed molecular level information, such as molecular positions and velocities at each time. Although the geometrical and the temporal scales in this simulation are quite limited owing to large computation efforts, microscale behavior of material and its meaningful properties can be estimated by statistical kinetics and thermodynamics models. The objective of the present study is to investigate the interfacial regions of liquid thread and their characteristics. In addition, this study focuses on the relation between the critical wavelength of perturbation and the equimolar dividing radius, and compares with the classical theoretical model given by the Rayleigh analysis[1].
