The present article reports numerical results of laminar natural convection heat transfer within an air filled semi cylindrical cavity with its horizontal walls submitted to different heating models. In this work, the horizontal surface is maintained at constant temperatures Tc (Dirichlet condition) or heat fluxes q (Newman condition), while that of the opposite surface is considered at cold temperature Tf. The parameters governing the problem are the Rayleigh number (103 < Ra < 106), and the Prandtl number (Pr = 0.71). The effect of thermal boundary condition on fluid flow and heat transfer is examined in the two cases. The comparison of the constant temperature and constant heating conditions lead to a strong change in the flow structure and the corresponding heat transfer. It is noted that with the increase in the number of Rayleigh, the intensity of the recirculation inside the enclosure increases.
