Abstract: Correlating equations for the film boiling heat transfer from a vertical cylinder of finite-length to subcooled water were refined. 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 and length of test cylinders used in the experiments are, 32mm x 16mm, 32mm x 32mm, 32mm x 64mm, 45mm x 45mm, 50mm x 16mm, 50mm x 32mm and 50mm x 64mm. The degree of liquid subcooling was varied from 2 to 30K. All the experimental data for the aspect ratio in 0.16 ≦ L/D ≦ 2.0 can be correlated within +-15% by the present prediction method.
