AB - 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 *T*_{H}. The lower wall is adiabatic and submitted to a vertical air jet while the upper wall is kept cold at a constant temperature *T*_{C} < *T*_{H}. 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 10^{5} ≤ *Ra* ≤ 10^{6}, 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.
