摘要：
A boundary integral equation formulation based on a reciprocal relation established in this article is developed for coupled heat-moisture transfer in porous media in the fully three-dimensional setting, including the internal sources of heat and mass, and the body forces. The fundamental solutions corresponding to singular sources of heat and mass respectively, necessary to develop the boundary integral equation scheme, are constructed. Selected numerical results are presented to demonstrate the features of temperature and moisture content distributions induced by the singular sources. The Laplace transforms of the boundary integral equations and the fundamental solutions are included and these provide a computationally efficient alternative to a direct time domain analysis.
