The effects of thermal conductivity of an inner body on heat-transfer phenomena in an inclined rectangular enclosure have been studied both numerically and experimentally. In the numerical analysis, the ratio of thermal conductivity of the inner body to that of the working fluid was varied parametrically. The numerical analysis was carried out for Pr = 10, Ra[sub w] = 5 [center dot] 10[sup 4] [approx] 5 [center dot] 10[sup 6] and inclination angles [gamma] = [minus]30 [approx] 60 degrees. The experiments were carried out with water. A Bakelite plate and brass plate were used for the inner body. The flow and temperature fields are presented in detail and the heat-transfer coefficient is discussed from these results. It is clarified here that the inner body with a large thermal conductivity enhances the heat transfer of the enclosure at large inclinations but suppresses the heat transfer for small inclination angles of the enclosure.
