Study on Fluid Flow and Thermal Characteristics in a Nanoscale Channel Using MD Simulation

분자 동역학 시뮬레이션을 이용한 나노 스케일 채널 내에서의 유체 유동 및 열적 특성에 관한 연구

To analyze the fluid flow and thermal characteristics in a nanoscale system, the planar Poiseuille flow of a Lennar-Jones liquid through parallel plates formed by fixed atoms is studied using nonequilibrium molecular dynamics simulations. The role of important simulation parameters such as the channel width, the magnitude of external field, the temperatures of the top and bottom plates, and the interaction potential parameter between fluid and wall atoms, which affect flow patterns and heat transfer rate inside the channel, are investigated. Under the various simulation conditions, interesting phenomena deviated from the continuum predictions have found.
