Abstract
Problems of heat and mass transfer involving a moving boudary are encountered in freezing, melting, diffusion of species with or without chemical reaction, evaporation, condensation, and in allied fields. In the present investigation the transient solidification of a finite slab of a binary alloy with a moving boundary is considered. The slab is taken to be superheated initially with a uniform temperature distribution. Solidification starts after one surface is cooled by convection while other surfaces are kept insulated. Temperature distribution and the position of moving boundary are determined by solving a non-steady-state energy equation analytically. Predicted results are compared with available experimental results and are found in good agreement.
