  • 摘要:The solutions of Maxwell and Rayleigh were the first of many attempts to determine the eective thermal conductivityof heterogeneous material. Early models assumed that no thermal resistance exists between the phases in heterogeneousmaterial. Later studies on solid-liquid and solid-solid boundaries revealed that a temperature drop occurs when heatflows through a boundary between two phases and, as a consequence, the interfacial thermal resistance should be includedin the heat transfer model. This paper is a review of the most popular expressions for predicting the eectivethermal conductivity of composite materials using the properties and volume fractions of constituent phases. Subject toreview were empirical, analytical and numerical models, among others.
