Abstract

The numerical schemes of the Dual Reciprocity Boundary Element Method are developed and used to simulate the problems of phase change and thermal wave propagation. The two-dimensional thawing characters of frozen working medium in microgravity heat pipe are presented in this paper. The superposition, resolution. reflection and phase jumping phenomenon of the thermal wave propagation in biological tissues are also shown in the paper. Introduction Recently, the Dual Reciprocity Boundary Element Method (DRBEM) is developed as the effective numerical method of pure boundary integral without domain integral ^. The DRBEM has been successfully applied to solve the problems as the
