On thermal waves and radiating heat transfer

Acta Physica Hungarica, 1991
Splitting up the heat flow into several parts and applying the basic ideas of Gyarmati’s wave approach of thermodynamics, a systematic thermodynamical analysis is given for radiating heat transfer. The possible transformations make clear that the above splitting can be done so that the different parts of the radiating heat transfer are independent of ...

A Thermodynamic Theory for Radiating Heat Transfer

Journal of Non-Equilibrium Thermodynamics, 1990
In a previous paper [1] we investigated what influence the scalar dynamic variables had on heat propagation. In this paper we study that of vectorial dynamic degrees of freedom. We point out that the phenomena described this way are heat propagation by electromagnetic radiation and/or acoustic waves and/or electron ...

Radiation Heat Transfer

1991
In this chapter, heat transfer by radiation in porous media is examined. The medium may be treated either as a single continuum or as a collection of particles (i.e., scatterers). In the particle-based analysis, the interaction of radiation with a collection of elements of the solid matrix (e.g., particles in a packed bed) is considered.

Solar Radiation and Heat Transfer

2017
Solar energy (i.e., from the Sun) is an ample source of energy in the universe. The Sun is responsible for all renewable energy sources to meet the need of all creatures (living organisms) such that their survival is not possible without solar energy reaching our planet. Solar radiation is the radiant energy emitted by the Sun (by way of nuclear fusion)

Radiation Heat Transfer

2000
Radiation Heat Transfer is an introductory text on radiation heat transfer. It starts from the basic physical principles of thermal radiation, and then goes on to develop methods for the calculation of view factors, rates of heat transfer between surfaces, effects of intervening gases, and the treatment of combined modes of heat ...

Heat Transfer by Radiation

2016
Heat transfer by thermal radiation is transfer of heat by electromagnetic waves. It is different from conduction and convection as it requires no matter or medium to be present. The radiative energy will pass perfectly through vacuum as well as clear air.

A paradox in radiation heat transfer

Resonance, 2007
Heat transfer between two surfaces usually increases when the temperature difference between the two surfaces increases. Here we highlight an unusual situation in radiation heat transfer wherein the heat transfer decreases when the temperature difference increases.

Heat Transfer in Radiation Gasdynamics

1966
The importance of heat transfer by radiation in engineering problems has been noticed for a long time such as the heat transfer in an industrial furnace. It has been studied by Kirchhoff more than 100 years ago. In such earlier investigations, we consider the heat transfer by radiation alone without the interaction with heat conduction and convection ...
