摘　　要：建立了人体-服装-微气候环境构成系统的数学模型,提出了该模型数值求解的边界条件.采用生物热方程与三维流场Navier-Stokes方程耦合求解的快速迭代算法,分别得到评价着装与不着装人体舒适问题的SD与EQT指标.数值结果表明:人体在着装与不着装情况下,数值结果与实验数据较吻合.Mathematical model of man-clothings-micro-climate system is built up and the boundary conditions of numerical solution for the model proposed. To evaluate thermal comfort for dressed and undressed body respectively based on SD and EQT indicator, coupled iteration method between three-dimensional Navier-Stokes Typical examples show that the numerical results equations and bio-heat equations is employed. are close to the experimental data both for the dressed and undressed body situation.
