Measurement of thermal diffusivity of polyester nonwovens using Artificial Intelligence

In the most of industries, the major applications of nonwovens are thermally insulating. Conventional methods are useless for measurement of thermal diffusivity of nonwoven layers hence the structure of nonwovens are complex with random fibres interaction. In This study, 16 different samples of commonly used polyester nonwoven layer which are different in thickness and weight were experienced by an apparatus designed to record temperature of both sides of samples in transient condition. A novel modeling method of heat transfer in transient condition based on actual samples via training of neural network has been applied to analyze heat transformation behavior of samples. The results of intelligent model are strongly confirmed by experimental results with good accuracy.
