Analysis of experimental data on melting and relocation of a metal melt on a cylindrical surface

The paper presents the results of experimental study on melting simulator of the fuel coating pin cladding made of alloy Pb (44.5 %)-Bi (55.5 %) and the flow of the melt on the surface of the heated rod. Experiments were conducted for different parameters: heat release, initial temperature, linear size, and the cladding thickness. All experiments provided the video of the process of formation and relocation of the melt, and the cladding temperature and mass loss rate were measured. The paper presents analysis of melt formation and relocation on the fuel rod imitator surface.
