抄録

The characteristic of boiling in a horizonatal channel with changing conditions of heated wall length and channel height have been studied experimentally. Behavior of bubbles on the heated wall and growth of bubble in the channel were observed by high speed camera at the experiment time. As a result, the behavior of growth of bubble which was classified into three types according to channel height had influence on time variation of degree of superheat, heat transfer and burnout heat flux in the channel. When the thickness of liquid on the bottom wall became thin, nucleate boiling with vapor dome was observed on the heated wall.
