Abstract: The solid temperature field of a vertical finite-length cylinder was numerically calculated with the convective boundary condition prescribed by a correlation equation proposed by authors for saturated film boiling heat transfer around a vertical finite-length cylinder. In order to examine the validity of the prediction, the experiments on the film boiling from a vertical test cylinder to a quiescent saturated water at atmospheric pressure have been carried out by a quenching method. The diameter and length of the test cylinder used in the experiment are, respectively, 45mm and 45mm and the cylinders are made of silver, copper, aluminum, carbon steel and stainless. The numerical values obtained by the finite difference method (explicit method) agreed well with the experimental data in terms of the cooling curve.
