Abstract
In this work, we use molecular dynamics simulation to describe the behaviors of fluids in nano-scale. For the reason, we logic Math equations and Physical behaviors by computer language and show them by movies and pictures. In this work, the behavior of nano-scale flow will be studied by molecular dynamics simulation to help us to understand behaviors that can not be discovered by experiment materials.Besides, a lot of behaviors of fluids such as bond-length、bond-angle、end-to-end distance、glass transition temperature can be disregarded in macroscopic point of view but have critical effects in the nano- scale systems. After checking the material, we will put it into spin coating system. By calculating the forces between each molecule with molecular dynamics simulation improve us to solve many problems.
