Аннотация

Numerical results are reported on the development of a melting front when a hot tube is suddenly brought in contact with a flat surface of solid sulphur. The liquid produced is continuously squeezed out while the gap width along the original "contact line" is maintained constant at 1.5 mm by application of a small but increasing force. The temperature of the hot surface is kept below 159 °C such that predominantly liquid would be present. The results show an initial rapid increase in the migration rate of the heat source followed by a near steady rate even when the surface has only been indented a little. The gap width increased in the azimuthal direction. The shape of the melting front, the liquid temperature and velocity profiles become nearly stationary soon after the melting zone has been established around a sector of the heating tubes. Temperature profiles were also similar at most of the intermediate polar angles.
