• 論文の詳細を見る

• The purpose of this study is to clarify the boiling characteristics in an inclined channel with rectangular section and the behavior of bubble generated from the heated upper wall experimentally and analytically. This channel is submerged into the saturated pure water bath at an inclination angle θ from the horizontal and both sides of the channel are opened. The value of θ is varied from 0 to 20°, the height of the channel is varied from 3 to 7mm and the heat flux supplied to die heated wall is changed. As a result, the behavior of coalescent bubble depends on the inclination angle and the channel height, and is classified into 4 types. Both the inclination angle and the channel height are predominant for the behavior of bubble and the characteristic of boiling. Moreover, in the case of θ=0°, burnout occurs easily because the heated upper wall is always covered with a coalescent bubble.
