Gallium Melting in a Rectangular Box
摘要
Numerical and experimental study of gallium melting in a rectangular box with a heated side face was
conducted. An advanced 3D numerical simulation, taking into consideration thermal variations of medium
properties and the presence of mushy zone, were performed and validated with experimental results. An
experimental setup, oriented to trace the liquid-solid interface position and profile and melt velocity using
ultrasonic Doppler velocity measurements in the liquid phase, was developed. The numerical simulation was
based on COMSOL Multiphysics software. 3D simulations were carried out to calculate melting regime
parameters and flow characteristics. The outputs of these simulations were compared with known
experimental data and new ones obtained on our facilities. An agreement between 3D computed and
experimental data indicates a profound effect of boundaries. Influence of the box dimensions on the process
characteristics was estimated numerically.
