B編}, month = {Aug}, note = {Correlating equations for the film boiling heat transfer from a vertical cylinder of finite-length to atmospheric subcooled water were examined and proposed. The overall heat transfer rate around the cylinder was determined by taking into account each convective heat transfer on the bottom, side and top surfaces of the cylinder. The present prediction method was compared with the experimental data obtained by quenching method. The diameter (D) and length (L) of the cylinder tested in the experiments are 32 mm×16 mm, 32 mm×32 mm, 32 mm×64 mm, 45 mm×45 mm, 50 mm×16 mm, 50 mm×32 mm and 50 mm×64 mm. The degree of liquid subcooling was varied from 2 to 30 K. All the experimental data for the aspect ratio with 0.32⪇L/D⪇2.0 can be correlated within ±15% by the present prediction method. Also, the lower limit of film boiling was discussed in terms of wall heat flux and degree of superheating., 日本機械学會論文集.
