本文基于多分量、多相流模型，重点研究服装组件中的热湿传递的数值研究，其中包括热/湿对流、传导/扩散以及相变。提出了一种分裂半隐式有限体积法来求解一组非线性对流扩散反应方程，其中纤维吸收的液态水含量的计算与其余计算分离。该方法保持空气、蒸汽和热通量（能量）守恒。研究了四种类型的服装组件，并与实验测量进行了比较。 AMS 科目分类：78M20、65N22、65N06
This paper focuses on the numerical study of heat and moisture transfer in clothing assemblies, based on a multi-component and multiphase flow model which includes heat/moisture convection and conduction/diffusion as well as phase change. A splitting semi-implicit finite volume method is proposed for solving a set of nonlinear convection-diffusion-reaction equations, in which the calculation of liquid water content absorbed by fiber is decoupled from the rest of the computation. The method maintains the conservation of air, vapor and heat flux (energy). Four types of clothing assemblies are investigated and comparison with experimental measurements are also presented.
