“…Therefore, spectral models are needed to describe the actual behavior of any real participating gas. Bratis and Novotny [11] were among the first to consider coupled radiation and natural convection using non-gray calculations and experiments in a differentially heated rectangular enclosure filled with a NH 3 -N 2 gas mixture. The same type of problem was later addressed by Fusegi et al [12,13] in a two-dimensional (2D) and then three-dimensional (3D) differentially heated cavity filled with anon-gray gas-soot mixture involving CO 2 and H 2 O.…”

A three-dimensional (3D) numerical study has been performed to investigate the effects of non-gray gas radiation on double-diffusive natural convection in a cubic enclosure filled with either air-H 2 O or air-CO 2 mixtures in cooperating situations. Gas radiation was taken into account by the discrete ordinates method (DOM) associated with the spectral line weighted-sum-ofgray-gases (SLW) spectral model. Results obtained for two average concentrations of H 2 O and CO 2 (10% and 20%) show that radiation modifies the temperature and concentration structures by creating oblique stratifications. The heat transfer rate is decreased, whereas mass transfer is not much modified. In addition, a comparison between 2D and 3D results is presented. ARTICLE HISTORY

“…The problem of radiative-convective flows for the fluids has been studied by several authors [8][9][10][11][12][13][14][15][16][17][18][19][20] in different situations and geometrical configurations. Goody [8] found an approximate solution of the problem of the onset of convection between plane-parallel plates heated from below when the fluid between them absorbs and emits the thermal radiations, he developed the equation of radiative transfer in two approximate forms, one appropriate to an opaque medium, the other to a transparent medium .Vedat S. Arpaci [9] studied the non-equilibrium interaction between thermal radiation and laminar free convection in terms of a heated vertical plate in a stagnant radiating gas .…”

In this paper, we use the Buongiorno's mathematical model for studying numerically the convective instability which is induced by a purely internal heating in a rotating medium confined between two isothermal surfaces and filled of a Newtonian nanofluid layer (water + alumina) in the case where the radiation heat transfer mode is taken into consideration, such that the nanoparticle flux is zero on the boundaries. The linear study which was achieved in this investigation shows that the thermal stability of nanofluids depends of the Coriolis forces generated by the rotation of the system, the thermal radiation parameter, the Brownian motion, the thermophoresis of nanoparticles and other thermophysical properties of nanoparticles. The studied problem will be solved by converting our boundary value problem to an initial value problem, after this step we will approach numerically the searched solutions using the power series method (PSM).

“…A study by Bratis and Novotny E8] for an enclosure is also available which shows the influence of thermal radiation and natural convection. However, for this complex system multidimensional effects are important and a two-dimensional model is presently being developed [8]. § 2.…”

The heat transfer and fluid flow are determined for fully deveIoped laminar flow in a vertical channel. The effects of natural and forced convection and thermal radiation are included in the analysis. The spectral variation of the radiation properties are included through the use of the total band absorp~ tance. The analysis is general and specific numerical results have been obtained for the 15 micron band of carbon dioxide. A simplified approach for large path is also presented which is in excellent agreement with the more exact results.
