The direct contact melting phenomena on a cylindrical heat transfer surface, set horizontally, is discussed analytically and experimentally. The basic equations for the thin liquid layer between the heat transfer surface and the phase change boundary are derived and normalized. Then, numerical calculations are performed over wide parameter ranges to get the liquid layer thickness distribution and the heat flux distribution on the heat transfer surface. The experiments are also performed using the water as the phase change material. The analytical and experimental results concerning the average heat flux at the heat transfer surface are found to agree well with each other. The exact solution for the heat flux distribution on the heat transfer surface is shown for the case of a small Stefan number, where the heat transfer through the liquid layer is approximated by the pure conduction.
