Three-dimensional analysis of heat conduction in anisotropic composites with thin adhesive/interstitial media by the boundary element method

摘要

Due to extensive applications in engineering practice, analysis of heat transfer in three-dimensional anisotropic composites has remained to be an important research topic. For the analysis, conventional numerical methods face modeling difficulties to different degrees when the thickness of component is very small. For this, modeling thin adhesive/interstitial media is usually ignored in conventional analyses. In this paper, two different boundary-element approaches are presented to model the heat conduction in three-dimensional anisotropic composites with thin adhesive/interstitial media. The first one is to weaken the singularity of the nearly singular boundary integrals, and the second is to implement a boundary-element conductance model without treating the thin media. All formulations have been implemented with illustrations of a few benchmark examples in the end.
