Summary

The paper reports the results of a numerical and experimental investigation of one-dimensional conduction-controlled cyclic melting and freezing. The phase change material was a plane slab, one surface of which was subjected to alternating periods of constant temperature above and below the fusion temperature while the other surface was insulated. Due to the cyclic change of temperature, multiple solid and liquid regions develop within the material. A front-tracking, self-starting finite-difference scheme was used to solve the resulting multiple moving boundary problem. Experiments were performed on n-octadecane in a thin horizontal cell with heat transfer from above.
