落下液滴の沸騰挙動と局所熱伝達変動との対応

抄録

An experiment was conducted to clarify the local heat transfer fluctuations in the boiling heat transfer of a falling droplet. In this report, a droplet was dropped on a heat transfer surface, and the boiling behavior was photographed by two high-speed cameras, one from diagonally above and the other through the heat transfer surface. At the same time, the heat transfer fluctuations were measured with an infrared camera. As a result, it was possible to measure the series of the process of formation, growth, and collapse of the boiling bubble with the corresponding fluctuations in heat flux distribution quantitatively.
