Effective Thermal Conductivity of Cloth With Moisture Diffusion

主要研究结果如下：1.在湿扩散传热条件下的温湿度分布测量首先，对实验室墙体和地面的隔热性能进行了改进，提高了测量精度。另一方面，当地湿度计是经过各种考虑和调查后开发的。2.考虑水分扩散和不考虑水分扩散时织物导热系数的比较织物的有效导热系数是指织物纤维中含有水分，但湿空气不流过织物，通过对一个模拟布料堆积的模型进行数值分析，研究了布料堆积的物理力学特性，比较含水量对温度分布和导热系数影响的局部行为，对模拟堆积布的简单模型进行数值分析。认为水在纤维小间隙中的粘附导致电导率的部分增加。

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.
