ABSTRACT = {This paper presents the results of numerical analysis of coupled laminar natural convection and surface radiation in a two-dimensional closed square 
cavity with the inversely linearly heated vertical opposite side walls and the adiabatic top and bottom walls. The cavity is filled with natural air (Pr =
0.70) as the fluid medium. In the present study, the governing equations i.e., Navier-Stokes Equation in the stream function - vorticity form and Energy 
Equation are solved for a constant property fluid under the Boussinesq approximation. For discretization of these equations, the finite volume technique 
is used. For the radiation calculations, the radiosity-irradiation formulation is used and the shape factors are calculated using the Hottel’s crossed-string 
method. The effects of pertinent parameters like Rayleigh Number (10<sup>3</sup> ≤ Ra ≤ 10<sup>6</sup>
) and the surface emissivity of walls (0.05 ≤ε≤ 0.85) are studied 
and analyzed.},
