BASIC HEAT TRANSFER AND SOME APPLICATIONS IN …
www.polydynamics.comthis chapter: Special Heat Transfer Problems in Plastics Processing. HEAT TRANSFER MODES Temperature differences cause the flow of heat from a high temperature to a low temperature. There are three modes of heat transfer: conduction, convection, and radiation. The basic microscopic mechanism of conduction is the motion of molecules and electrons.

Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. The Electromagnetic Spectrum Radiation is one way to transfer heat. To “radiate” means to send out or spread from a
