摘要
分析含湿多孔介质内部的传热传质过程及其热湿传递特性参数 ,建立一维热湿迁移过程方程组 ,通过特征函数法解出多孔介质内部温、湿度分布 ,由测试值作非线性最小二乘拟合 。
By analyzing heat and mass transport process and transport properties of moist porous media, this paper established a computational model for one dimensional field of heat and moisture transport process. Based on the distinguishing characteristic functions, the inner temperature and humidity distribution of porous media was worked out. With the actual spot measurement, the heat and moisture properties were obtained by nonlinear least square method.
