Abstract

The boundary element method is developed for the solution of Stefan problems in a semi-infinite domain with constant properties and imposed with constant or timevariant temperature and flux boundary conditions. The medium may or may not be superheated or subcooled and the boundary element results are obtained with a dissection method. Numerical data indicate that the boundary element results are almost as accurate as those of a source-and-sink method which has demonstrated to be highly accurate in previous studies. The advantages of the boundary element method are also given in the paper.
