Top Flooding in Thin Rectangular Channels

概要

論文の詳細を見る
In the previous study, top flooding in thin rectangular channels could be characterized by using the wider span W as a characteristic length in the Wallis nondimensional velocity. To further study the flooding characteristics related to the span W, top flooding experiments in thin rectangular channels of different spans W were conduct-ed. When liquid penetration into the channels was small, the span W was the most important characteristic length. However, when the liquid penetration was large, the span W was not an appropriate scale. The nonuniform distributions of void fraction and velocity in the spanwise direction can be represented by the span W in the low liquid penetration region. However, in the high liquid penetration region, random penetration of liquid along the spanwise direction mitigated the role of W.
