Abstract

The role of natural convection on the solid-liquid interface motion during melting from above and solidification from below of a pure metal was studied. The measurements of both temperature distributions and temperature fluctuations were used as a qualitative indication of the natural convection flow regimes and structures of melt during phase transformation. The photographs of the solid-liquid interface morphology (after draining the melt from the test cell) revealed complicated time-dependent flow structure in the liquid. The measured (average) and predicted solid-liquid interface positions during solidification from above and of melting from below show reasonably good correspondence.
