Experimental investigations have been carried out concerning natural convection on a heated plate with a slight inclination from horizontal. Local heat transfer coefficients were measured for three inclined plates of 5°,10°,15°and a horizontal plate. The fluid flow and wall temperature fields were also visualized using a fluorescent paint and liquid crystal sheet, respectively. It was found from the visualization that the low temperature streaks appeared on the surface near the lower and upper edges of the inclined plate below 10°and that the downward flow from the upper edge of the plate appeared, but it did not disappeared in the inclined plate of 15°. Local heat transfer coefficients from the upper edge toward the center of the plate increased remarkably when the downward flow appeared. By introducing a nondimensional parameter, these experimental results with visualization on the temperature and flow fields and also with the local heat transfer coefficients were rearranged quantitatively and effectively.
