Experimental study on convective heat transfer through fibrous insulators

Popis výsledku v původním jazyce

In high-loft fibrous insulators, heat transfer involves three modes, conduction, radiation and convection. Heat transfer by conduction and radiation are widely investigated, however, due to the complexity of fluid flow convective heat transfer through fibrous materials is not well experimentally studied. The aim of this work is to study heat transfer by forced convection through fibrous insulators using a dynamic heat transfer tester which is self-refited on the basis of particle image velocimetry. Five levels of airflow velocity under the condition of both preheating and continuous heating are used for measurement to discuss the convective heat transfer behavior of different nonwoven fabrics. The effect of airflow velocity, heating condition as well as structural parameters of nonwoven fabrics will be compared and analyzed. The results of this work can help further understand the convective heat transfer through fibrous insulators.
