Mathematical model of heat transfer in PCM incorporated fabrics subjected to different thermal loads

Maciej Jaworski

Abstract

Impregnation of textiles (fabrics) by phase change materials (PCMs) changes their thermal properties. High thermal capacity of PCMs, due to large enthalpy of phase change (latent heat), increase the potential of these materials for heat accumulation, but also modifies heat transfer in transient states what improves their insulating characteristics. The paper presents selected results of the research that was focused on the development of mathematical and numerical models of heat transfer in the fabrics laminated by the layers containing phase change materials. Different modes of interaction with the environment were taken into account, including radiative heating, cooling in natural convection and direct contact of the fabric with a solid body of large thermal capacity. The models were validated with the use of experimental measurement of thermal performance characteristics of the fabrics with PCM incorporated. Validation allowed also quantitative identification of some parameters characterizing heat transfer both inside the fabrics and interaction with the environment, such as absorption an transmission coefficient for radiation. In the study the real thermal characteristics of the fabrics were used, e.g. enthalpy vs. temperature determined with the use of DSC. Overall thermal characteristics of the textiles, i.e. temperature variations under different thermal loads, are also presented in the paper.
