摘要

Molecular dynamics process, in which diatomic molecules, nitrogen, flow over aluminum crystalline surface, is investigated. For the purpose of generating liquid flow in the system a certain boundary condition taking account for inflow and outflow of molecules is devised. Morese potential is adopted to atomic interaction in solid aluminum and Lennard-Jones potential with rigid-body treatment is used for nitrogen molecules in the liquid state. Regional heat flux is calculated over flowing liquid nitrogen region. It is shown that heat transfer from the aluminum body can be realized by temperature control in solid and that the magnitude of heat flux depends on the temperature gradient across the interface between solid part and liquid part.
