Résumé

Results are presented of a finite element computational study of the free convection-dominated melting of a pure phase material contained in concentric horizontal annuli of different configurations. Effects of the Rayleigh number as well as heating of the inside, outside or both walls at a temperature above the melting point of the material were studied. Flow and temperature patterns within the melt, local heat flux distributions at the heating surface and the cumulative energy charged as a function of time are presented and discussed.
