TL;DR: In this article, the fundamentals of near-field thermal radiation, photon entropy, and nonequilibrium effects in semiconductor diodes that underpin device operation are discussed in detail, and remaining challenges and opportunities for progress are identified.
Abstract: Radiative thermoelectric energy converters, which include thermophotovoltaic cells, thermoradiative cells, electroluminescent refrigerators, and negative electroluminescent refrigerators, are semiconductor p-n devices that either generate electricity or extract heat from a cold body while exchanging thermal radiation with their surroundings. If this exchange occurs at micro or nanoscale distances, power densities can be greatly enhanced and near-field radiation effects may improve performance. This review covers the fundamentals of near-field thermal radiation, photon entropy, and nonequilibrium effects in semiconductor diodes that underpin device operation. The development and state of the art of these near-field converters are discussed in detail, and remaining challenges and opportunities for progress are identified.

TL;DR: In this article, the authors modify the Pennes model by taking into account the thermal relaxation time of biological tissue, and employ the Maxwell-Cattaneo thermal flux law, in conjunction with the fourth power law, to model the effects of high thermal radiation on such skin.

TL;DR: In this paper, the steady flow of incompressible, viscous, conducting and optically thin fluid over a vertical plate with magnetohydrodynamic mixed convection, thermal radiation and viscous dissipation was investigated.

TL;DR: In this paper, the thermal radiation intensity from a series of large outdoor jet fire experiments was estimated by applying the solid flame model in both one-zone and multiple-zone configurations (taking into account the variation of surface emissive power), considering the flame as a cylinder defined by the 800 K isotherm.
