Abstract: 
In this work, Boltzmann transform has been used to analyze the problem of freezing ‎of pure Aluminum in semi-infinite domain. The uniqueness of solution (solidification ‎front location) has been proved using the characteristics of the functions appeared in ‎solution. The effect of density change on temperature distribution and errors resulting ‎from ignoring this change have been investigated. The solidification problem in finite ‎media was solved using the boundary element method (BEM), with quadratic shape ‎functions. The applicability of the fundamental solution, as weighting function in ‎BEM, in finite domain has been investigated. The accuracy of the method is ‎illustrated through one-dimensional numerical examples. Some careful experiments ‎were carried out, using the facilities of the School of Metallurgy and Materials at the ‎University of Birmingham, UK, to obtain the data. Comparison of theoretical, ‎numerical and experimental results revealed that good agreement exists between ‎them. However, minor differences were observed due to imposing of the simplifying ‎boundary conditions. The effects of density change may be ignored in small volumes, ‎but they must be taken into account in real applications‏.‏
