摘要

A boundary element formulation fo rthe solution of multiple moving boundary problems is presented and tested herein. A heat transfer problem involving heating of solid, mlting of solid and vaporisation of liquid is considered. Numerical results show that te boundary element method is move suitable and more accurate than both finite difference and finite element methods for this kind of problems.
