摘要
运用局部热源法对墙体传热系数的现场检测作了实验研究。建立实验研究模型,现场测得了实验分析中所需的各物理量,针对实验墙体编制了三维非稳态传热程序,对实验墙体的传热系数进行神经网络辨识,并作了简要误差分析。测试结果与理论值接近。
An experimental study on in-situ measuring coefficient of thermal conductivity of wall by method of local heating was conducted. All physical parameters needed were measured using the experimental model and the thermal conductivity coefficient of wall was determined by neural network method based on a tri-dimension unstable thermal conduction computer program. The experimental results show a perfect correlation with the theoretical values.
