The natural convection heat transfer of fluids with two-layer stratification in an inclined enclosure was investigated by numerical analysis of F.E.M.. Two kinds of combination of stratified fluids were used to describe the heat transfer rate, and the flow and temperature fields in detail in the range of Raw<1.2x10^4. The inclination angle of the enclosure was varied from 32° to 148° and the aspect ratio (height/width) of the cross-section of the enclosure was 2. It was shown that the quantity of heat Q_B transferred through the boundary surface of the two stratified fluids varied widely with the inclination angle and the Rayleigh number of each fluid. And the quantity of heat through the hot and the cold walls was influenced significantly by the quantity of heat Q_B.
