B編, Transactions of the Japan Society of Mechanical Engineers, Part B}, month = {Aug}, note = {The film boiling heat transfer around a vertical silver cylinder with a convex hemispherical bottom was investigated experimentally for quiescent water at atmospheric pressure. The experiments have been carried out by a quenching method. The diameter and length of test cylinder are 32mm and 48mm, respectively. The test cylinder was heated to about 600℃ in an electric furnace and then cooled in saturated or subcooled water with the immersion depth of about 100mm. The degree of liquid subcooling was varied from 0K to 30K. The analytical solutions for saturated and subcooled boiling are obtained by applying the two-phase boundary layer theory for the vapor film with the smooth interface. The experimental data can be correlated within ±15% by the present prediction method. Also, the lower limit of film boiling was examined in terms of wall heat flux and degree of superheating., 日本機械学會論文集.
