  Citation × Citation Citation Abstract Copy Title: An experimental investigation of transition pool boiling Author: Aoki, Tadao The heat-transfer phenomena studied in this work were associated with pool boiling from a flat horizontal surface facing upward with the bulk liquid at its saturation temperature. The analysis of boiling sound and the investigation of the transition boiling mechanism constituted the essence of the present study. The distinctively large sound intensity with predominant frequency components of 250 Hz and 500 Hz was observed during transition boiling. From the photographic studies of surface temperature variation, it was concluded that the heat transfer mechanism at relatively low heat flux levels of transition boiling involves the direct contact between liquid and the hot surface followed by a spheroidal state of the liquid. At higher heat flux levels while the liquid was in the spheroidal state, its contribution to total heat transfer increased with a decrease in surface temperature.
