Modes of Transferring Heat - Heat Transfer

Heat Transfer Engineering | Thermodynamics

  • Heat is always transferred when a temperature difference exists between two bodies. There are three basic modes of heat transfer:
  • Conduction involves the transfer of heat by the interactions of atoms or molecules of a material through which the heat is being transferred.
  • Convection involves the transfer of heat by the mixing and motion of macroscopic portions of a fluid.
  • Radiation, or radiant heat transfer, involves the transfer of heat by electromagnetic radiation that arises due to the temperature of a body.
