Paper Abstract

For the purpose of explaining the correlation of the heat transfer characteristics and the steam bubble behavior, the boiling phenomena were observed. The heating surface was the horizontal Pt-wire, and shaken periodically for the normal direction to the axial direction in the saturated distilled water. Also, this was a continuous and smooth motion. The experimental condition was performed for atmospheric pressure. The observations were using shadow-graphy with a high speed video camera and a still camera. In the consequence of the present experiments, the high burn-out heat flux and the high average heat transfer coefficient were obtained by the comparison with the still heated surface. Also, by the visualization of the quantity of the bubble population on the shaking surface, it was observed that the quantity decreased by the comparison with the still heated surface. It was conjectured that the present phenomena were caused by tearing the overheated liquid, and by promoting of departing of steam bubble on the heating surface. The detailed research of the generating and departing of bubble with periodically moving heated surface is expected. Also, the research of the boiling characteristics by changing the frequency of the motion is expected.
