Abstract

When an electromagnetic wave interacts with participating media
(e.g. particulate media); the intensity of the radiation may be changed by the absorption,
emission and scattering phenomena. Subsequently, the incident radiation will be
attenuated and/or augmented under the effect of these phenomena. Light
scattering and absorption by small particles are quite important in a wide
range of applications such as meteorology, biomedicine, biophysics, astronomy,
combustion, fire and flame, and solar thermal applications. Particulate media
have been introduced as a working medium to improve the efficiency of thermal
systems such as solar thermal power plants. The efficiency of the direct
absorption solar thermal collectors (DASC) can be improved by using particulate
media because of the unique thermo-optical properties, which in turn leads to
enhance the thermal performance. The main objective of the present study is to
investigate the effect of the participating media in the volumetric heat
generation under the concept of photo-thermal energy conversion.
