Experiments of the convective heat transfer in an inclined air filled rectangular cavity were carried out under the conditions of angle of inclination from 0° to 180° and a wide range of aspect-ratios (H/W = 5 〜 83). Depending on the angle of inclination, three flow pattern modes of a three-dimensional Benard cellular flow, a screw type flow with the axis parallel to the direction of inclination and a two-dimensional boundary layer flow were identified by visual observations of two directions. In addition, useful correlations of non-dimensional heat transfer coefficients were derived in the relations between Nusselt number Nu_W and modified Rayleigh number Ra_W cosθ or Nu_W and Ra_W sineθ.
