SUAREZ CASTANEDA, Jose Luis; AMELL ARRIETA, Andrés Adolfo  and  CADAVID SIERRA, Francisco Javier. Infrared Radiation as Heat Transfer Mechanism of High Quality in Heating Processes. ing.cienc. [online]. 2012, vol.8, n.16, pp.97-127. ISSN 1794-9165.

This paper tries to address the infrared radiation as a primary mechanism of heat transfer of high-quality in different heating processes, to highlight the issues and applicability in the use, the characterization and design of the technologies powered by combustion systems. For this, it summarizes its phenomenology, definitions, assumptions and solutions; addresses some numerical methods used to solve the Radiative Transfer Equation (RTE) and its coupling to CFD codes (Computational Fluids Dynamics); as also the types of radiant equipment usually used, in especial the radiant tubes; as well as certain experimental methodologies used to characterize radiant systems, and some design methodologies. It was found, that the flux model and the discrete transfer are sufficient to give solution to the radiation heat transfer phenomenon with the help of CFD codes, as well as the measuring device mainly used in experimental measurements is the radiometer, and the most practical design methodology may be the optimization.

Keywords : infrared radiation; radiant tube; radiant heat; thermal radiation.
