Research Abstract

This study discussed on thermal and flow characteristics in direct contact type heat exchanger. It focused on droplet behavior, in other word, microscopic viewpoint. The result revealed the effect of nozzle and feed conditions on the droplets formation, ascending and separation behaviors. The experiments including phase change phenomena clarified the variation of inside state and flows in the exchanger. These results enabled the quantitative analyses on heat exchange, heat storage and release rate.
