Film Boiling Heat Transfer on an Oscillating Surface

Film boiling occurs when the wall temperature is so high that the vapor layer exists between the heating wall and the liquid. Various works have been made to investigate the film boiling heat transfer. However, they are limited to the stationary heating wall. Recently, a marine reactor receives a great attention. The ship may show six-degree-of freedom motions in response to external conditions such as ocean waves. Of six motions, the heaving linear oscillation and the rolling rotational oscillation are relatively important in terms of length scale. The objective of this study is to investigate the effect of the wall oscillation on the heat transfer. Toward this end, we performed volume-of-fluid simulations. This study seems the first in the film boiling on a moving surface. The effect of the oscillation on the film boiling heat transfer will be investigated numerically. The result will be presented in the conference.
