Popis:	This paper presents the numerical study of the laminar mixed-convection heat transfer of two identical protruding heat sources mounted in an inclined channel with obstacle. The control volume method and the SIMPLER algorithm are used to solve the dimensionless governing equations of mass, momentum, and energy for mixed convection. The effects of the obstacle, the channel inclination and the Reynolds number 5 ≤Re≤ 30 on streamlines and isotherms as well as on the heat transfer rate at the surface of each component are investigated for Pr=0.71 and Gr=105. The finding results show that for the channel inclination angle in the range 30° ≤φ≤60°, the obstacle has a large effect on the rate of transfer. In addition, by analyzing the effect of the obstacle size, it has been found out that the obstacle height has a strong effect on the cooling rate of the area between the two sources while the obstacle width effect is less noticeable.
