ABSTRACT = {A numerical mixed convection investigation was carried out to study the enhancement of heat transfer in a square cavity with identical heated rectangular blocks adjacent to its upper wall, and submitted to a vertical jet of fresh air from below. The configuration so defined is an inverted "T"-shaped cavity presenting symmetry with respect to a vertical axis passing by the middle of the openings. The governing equations have been solved using the finite difference method. The parameters of this study are: Rayleigh number 10<sup>4</sup> ≤ Ra ≤ 10<sup>6</sup>, Reynolds number 1 ≤ <i>Re</i> ≤ 1000, the opening width C=0.15, the height of blocks B=1/4, 1/2 and 3/4. The non-dimensional space between blocks and geometric parameter of the cavity are kept constant (D=0.5 and A=1). The results obtained, with Pr=0.72, show the validity of different solutions, when varying Re, Ra and B, on which the resulting heat transfer depends. Some useful correlations are also proposed.},
