“…Consideration of thermal radiation with and without conduction is important in the analysis and design of a wide range of thermal systems [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. If its consideration is paramount in the design and operation of high temperature thermal systems like boilers and furnaces [1,13], it plays an important role in the thermal analysis of phase change processes of semitransparent materials, such as glass and silicon [8].…”

“…Heat transfer in porous insulations in the space shuttle is mainly by conduction and radiation [4,5]. Thermal radiation is a dominant mode of heat transfer in devices based on C⃝ 2016 Wiley Periodicals, Inc. porous media combustion [6,7]. These days, it has found applications in the diagnosis of tumors in the human body, and various types of laser based surgeries [9][10][11].…”

Radiative heat transfer with and without conduction in a differentially heated 2-D square enclosure is analyzed. The enclosure with diffuse gray boundaries contains radiating and/or conducting gray homogeneous medium. Radiatively, the medium is absorbing, emitting and scattering. On the south boundary, four types of discrete heated regions, viz., the full boundary, the left one-third, left two third and middle one third, are considered. In the absence of conduction, distributions of heat flux along the south boundary are studied for the effect of extinction coefficient. In the presence of conduction, distributions of radiation, conduction and total heat fluxes along the south boundary are analyzed for the effects of extinction coefficient, scattering albedo, conduction-radiation parameter, and south boundary emissivity. Effects of these parameters on centerline temperature distribution are also studied. To assess the performance of three commonly used radiative transfer methods, in all cases, the radiative transfer equation is solved using the discrete ordinate method (DOM), the conventional discrete ordinate method (CDOM) and the finite volume method (FVM). In the combined mode problem, with volumetric radiative information known from one of the three methods, viz., DOM, CDOM, and FVM, the energy equation is solved using the finite difference method (FDM). In all cases, the results from FDM-DOM, FDM-CDOM, and FDM-FVM are in good agreement. Computationally, all three sets of methods are equally efficient. C⃝ 2016 Wiley Periodicals, Inc.

An analytical model for one-dimensional premixed filtration combustion of volatile fuel particles-air mixture is presented. It is presumed that fuel particles first vaporize and a gaseous fuel with definite chemical structure is formed, which is subsequently oxidized in the gas phase. Flame structure is considered in the three zones. In the preheating vaporization zone, the mixture is heated until it reaches ignition temperature. In the reaction zone, the combustible mixture burns and the post flame zone is occupied by the combustion products. The temperature and mass fraction profiles are obtained of gaseous fuel in these three zones at a semi-infinite inert porous media. Thereafter, the effects of various parameters such as gas velocity, porosity, fuel particles diameter, number density of fuel particles, and heat of chemical reaction on the temperature and mass fraction profiles are investigated.

“…Kayal and Chakravarty [17] presented a numerical analysis of combustion of submicron carbon particles inside an inert porous medium where the particles in form of suspension in air entered the porous medium. In this study, a one-dimensional heat transfer model was developed using the two-flux gray radiation approximation for radiative heat flux equations, and the effects of absorption coefficient, emissivity of medium, flame position and reaction enthalpy flux on radiative energy output efficiency were considered.…”
