—This paper presents a numerical analysis of the effects of radiation on natural convection flow and heattransfer inside the asymmetrically heated convergent channels formed by two flat plates. One of the side walls is orientedvertically and is thermally insulated, and the opposite wall is tilted to various degrees to form convergent angles and isheated uniformly with a constant heat flux. Air (Pr 0.71) is considered as the working fluid. The flow is assumed to besteady-state, two-dimensional, laminar, and incompressible with negligible viscous dissipation. Results in terms of walltemperature profiles as a function of the wall inclination angle, channel aspect ratio and the heat flux are given for twovalues of the wall emissivity. Flow visualization is also carried out to show the peculiar pattern of the flow between theplates in several configurations. Dimensionless maximum temperatures are correlated to the Rayleigh number, in theinvestigated range from 102to 108and 0° ≤ ???? ≤ 10 .
