Effective Thermal Conductivity of Cloth With Moisture Diffusion

本研究的主要结果如下：1。在水分扩散传热的情况下，测量湿度和温度的分布。首先，为了提高测量精度，对实验室墙面和地板的保温性能进行了改进。另一方面，当地的湿度计是经过各种考虑和调查后发展起来的。用该仪器测量了布堆试件上的湿度分布。有水分扩散和无水分扩散时导热系数的比较。织物纤维中含有水分，但潮湿空气不通过织物的有效导热系数，在案例1.3的测量后，用非定常探头法测量。布堆模型的数值分析。为了研究或比较含水量对温度分布和热导率的局部影响，对一个简单的模拟堆布模型进行了数值分析。认识到水在纤维缝隙中的黏附导致了电导率的部分增加。

Main results obtained in this study are as follows :1.The measurement of humidity and temperature distributionin case of heat transferred with moisture diffusion.Firstly the improvement of insulating performance of wall and floor in laboratory room has been done for better measurement accuracy. On the other hand, the local hygro-meter was developed after various consideration and surveys. By employing this meter, humidity distribution was measured on the specimen constructed by piled cloths.2.Comparison of thermal conductivity with moisture diffusion and without of it.Effective thermal conductivity of cloth contained the water in its fibers, but moist air do not flow through it, is measured by unsteady probe method after the measurement of case 1.3.Numerical analysis on a model that simulate the piled cloths.To investigate or compare local behavior of water content that affect temperature distribution and thermal conductivity, numerical analysis applied to a simple model simulated piled cloths. It is recognized that the sticking of the water in the small gaps of fiber cause partial increase of conductivity.
