Resumen

In this work the numeric results, of the heat transfer by natural convection in a tilted open cubic cavity are presented. The most important assumptions in the mathematical formulation are two, the flow is laminar and the Boussinesq approximation is valid. The conservation equations in primitive variables are solved using the finite volume method and the SIMPLEC algorithm. The advective terms are approximated by the SMART scheme and the diffusive terms are approximated using the central differencing scheme. The results in the steady state are obtained for a Rayleigh range from 104 to 107 and for a range 0°-180° of the inclination angles of the cavity. The convective Nusselt number changes substantially with the inclination angle of the cavity. The numerical model predicts Nusselt number oscillations for low angles and relative high Rayleigh numbers (105-107).
