WebSep 9, 2024 · Heat flows in the opposite direction to the temperature gradient. The ratio of the rate of heat flow per unit area to the negative of the temperature gradient is called the thermal conductivity of the material: (4.3.1) d Q d t = − K A d T d x. I am using the symbol K for thermal conductivity. Other symbols often seen are k or λ. WebAs environment-friendly building materials, earth materials are attracting significant attention because of their favorable hygrothermal properties. In this study, the earth materials in northwest Sichuan were tested and curves of thermal conductivity and water vapor permeability with relative humidity were obtained. The function curves and constants of …
