| 摘 要： | 简述了局部热平衡模型和局部非热平衡模型的基本概念,并分别对局部热平衡模型的有效性问题和局部非热平衡模型的边界条件进行了讨论,从流态、多孔介质骨架材料和研究尺度3个角度对局部非热平衡模型在多孔介质热质传递领域的应用进行了系统的总结。针对低导热系数内的局部非热平衡效应,提出了一种基于局部非热平衡模型的等效球简化法,该方法较为准确地获取了低导热系数固体和流体的温度。为多孔介质局部非热平衡模型的使用和进一步研究提供借鉴。

| Abstract: | The basic conceptions of local thermal non-equilibrium (LTNE) model and local thermal equilibrium (LTE) model are described in this paper.The validity of LTE model and boundary condition of LTNE model are also discussed.The application of LTNE model in porous media is systematically summarized based on flow state,solid matrix of porous and study scale,respectively.We propose an equivalent sphere method based on LTNE model to investigate the LTNE effects in porous media with small thermal conductivity and obtain more accurate solid and fluid temperatures.The paper can provide important reference for the use and further theory study of LTNE model for the porous media. |
