We study the effect of inclination angle on mixed convection in a "T" form cavity containing two openings and two heated blocks mounted on its lower wall. The blocks are maintained at a constant temperature TH. The lower wall is adiabatic and submitted to a vertical air jet while the upper wall is kept cold at a constant temperature TC < TH. The vertical walls are rigid and adiabatic. The governing equations are solved by a finite volume method. Special attention is devoted to the solution symmetry, the flow structure and the heat exchange through the cavity. The considered control parameters are: the inclination angle 0° ≤ φ ≤ 90°, the Rayleigh number 105Ra ≤ 106, the Reynolds number 100 ≤ Re ≤ 1000, the Prandtl number Pr=0.72, the height of the blocks B=0.5, the opening width C=0.15 and the distance between blocks D=0.5. The results are presented in terms of streamlines, isothermal lines and variations of Nusselt number with Re or φ.
