Abstract

This paper provides an overview of our recent theoretical and experimental investigations into the complex phenomenon of heat and moisture transport through porous fibrous insulation aimed at improved understanding of the mechanisms involved. Our improved transient model, integrating conductive and radiative heat transfer, moisture diffusion, moisture bulk flow, moisture sorption and desorption as well as phase change were validated by subzero experiments on a novel sweating guarded hot plates. Our work is further extended to optimize the porous fibrous insulations for maximizing the thermal insulation and moisture transmission for various applications.
