“…The cooling system of next generation nuclear reactors are expected to remain functional even when the pump is not working. Natural convection can be used to flow the coolant without using a pump (Abdillah and Novitrian, 2019). One of the prime criteria for safe design of an electronic equipment is its cooling performance by unaided natural convection.…”

The results of numerical analysis of coupled laminar natural convection and surface radiation in a two-dimensional closed square cavity with the uniformly heated bottom wall, linearly heated vertical side wall(s) and the adiabatic top wall is discussed. The cavity is filled with natural air (Pr = 0.70) as the fluid medium. In the present study, the governing equations i.e., the Navier-Stokes Equation in the stream function -vorticity form and the 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 by using the Hottel's crossed-string method. The effects of pertinent parameters like the Rayleigh Number (10 3 ≤ Ra ≤ 10 6 ) and the surface emissivity of walls (0.05 ≤ε≤ 0.85) are analyzed.
