Radiative heat transfer can also be referred to as thermal radiation or infrared radiation. It is the emission of energy in the form of electromagnetic waves from a heated surface. This process can also be described as heat transfer by radiation or radiant heat transfer. Another name for radiative heat transfer is radiation heat exchange, which describes the exchange of thermal energy between two surfaces through electromagnetic waves. This type of heat transfer is often used in space heating and cooling systems, as well as in industries such as metallurgy and ceramics. It is important to understand the different synonyms for radiative heat transfer to accurately communicate during scientific discussions or research.
