RESUMO

The processes of energy transfer at the thermal level are discussed from the standpoint of atomic or molecular motions on problems of heat conduction and radiation. By discussing the description of the thermal motions of atoms and molecules, the heat flux and the temperature are defined to be related to the continuous thermal-fluid dynamics. Molecular motions can be predicted with the molecular dynamics method provided an appropriate potential is given for their motions. Even with a qualitative function of the potential, detailed features or characteristics of heat transfer can be understood on molecular levels which are required for advanced thermal technology of high-speed and fine-precise controlling; what and how motions of atoms and molecules control the heat transfer, by interacting and correlating each other.
