Abstract

In an inclined enclosure with the upper part cooled and the lower part heated, quantitative data of the temperature and velocity are obtained simultaneously using thermo-sensitive liquid crystals. Experimental results are presented for Pr=909, aspect ratios of 1/14, 2/14 and 3/14, angle of inclination, 0≤≤45 to the horizontal line. The numerical results are obtained in the same conditions as experiments by the finite volume method and its results are compared with experimental results. It is found that the number of cell is decreased with increasing the angle of inclination, and a unicell is formed at nearby =30° which is not affected by the aspect ratio.
