Abstract	:	This study represents the numerical solutions of the buoyancy driven turbulent flows in an inclined two dimensional rectangular enclosure in which one of the vertical walls is heated and the other is cooled. Low Reynolds number extension of the two equation usdk-\varepsilonusd model is used to model the turbulent flow. The effect of various parameters such as the number partitions, the angle of inclination and the Rayleigh number on the flow field and the average Nusselt number have been investigated and presented. The results indicate that the insertion of a single partition having a finite thickness and thermal conductivity reduces significantly the average Nusselt number. The rate of reduction decreases as more partitions are added. The results also indicate that there is an optimum angle of inclination at which the maximum average Nusselt number occurs and that the average Nusselt number increases as the Rayleigh number increases.
