A method for calculating the effective thermal conductivity of moisture-containing highly porous foamed polymers is proposed. In this method a non-additive scheme for taking into account the effect of steam diffusion on heat transfer is used. The sequential binary systems (interstitial substance from a liquid and a vapor- gas mixture. as well as a polymer skeleton and an intra-porous ... https://cosmeticssquadets.shop/product-category/toys/
