n (1794) The net transfer of heat from a hotter body to a cooler one by (usually infrared) radiation. Radiant transfer is one of the three basic mechanisms of Heat Transfer requiring no contact or fluid between the bodies. The net rate is proportional to the differences between the fourth powers of the absolute temperatures of the hotter and cooler bodies \(\left( {T_1^4 - T_2^4 } \right)\), and depends also on the thermal “color” of the bodies (their emissivities), their geometries, and their positioning relative to each other. The principal use of radiant heating in the plastics industry is in Sheet Thermoforming. See Infrared Drying (or IR Drying) (Strong AB (2000) Plastics materials and processing.
