Natural convection heat transfer of fluids with two-layer stratification in an inclined rectangular enclosure was studied. The experiments were carried out for stratified fluids such as spindle oil-pure water for the Rayleigh numbers in the range of Raw_I (spindle oil)=8.1X10⁶-3.5X10⁷ and Raw_II (pure water)=3.8X10⁷-1.6X10⁸, and an aspect ratio H/W=2. The velocity and the temperature fields and the heat transfer coefficient were investigated at several inclination angles of the enclosure. It was clear for the inclined enclosure that the configuration of each fluid region, varying with the inclination angle, significantly effects the heat transfer coefficient.
