Numerical simulation of dynamic heat-moisture transfer within the human-clothing-environment system

Abstract

建立了人体 -服装 -环境系统的动态热湿传递模型。对Stolwijk人体热调节模型进行了改进 ,考虑到了汗水的积聚过程 ,并结合织物热湿耦合模型 ,用于人、服装、环境系统的瞬态热湿传递过程的数值模拟。在模型中 ,考虑了纤维对湿的吸附与解吸过程及其对热传导率、热容的影响 ,以及相变导致的热生成及释放。实验表明了模型的良好预测性能 Establish the Stolwijks human thermal regulatory model, take the accumulative course of perspiring into consideration, then combine the heat-moisture transfer model of fabric for numerical simulation of instantaneous status heat-moisture transfer course in human-clothing-environment system. The phenomenon that the fiber can adsorb and desorb moisture is the problem at core on study into the comfort property of clothes which is bound up with dynamic heat-moisture transfer.The effects of the thermal conductivity rate,thermal capacity as well as heat occur and release due to phase change also be taken in consideration as the model set up.Experiments show the model possess a good predictability.
