The calculated model development algorithm for the transfer of thermal energy through porous and fibrous-porous structures is presented. This algorithm allowed to reduce the complexity of work in determining the effective coefficient of porous constructions thermal conductivity. © 2022 The Authors. Published by ELSEVIER B.V.

Introduction Structural integrity is the ability of a structure to withstand its intended loading without failing due to fracture, deformation, or fatigue. It is a concept often used in engineering to produce items that will serve their designed purposes and remain functional for a desired service life. When structural failure porous materials, it often raises the question of determining the effective thermal conductivity of a new material or known porous material when it is compacted. The study of structural processes in porous materials is a separate direction of thermophysics because the structure of porous materials provokes the flow of complex heat and mass transfer processes: transfer of thermal 1st Virtual International Conference “In service Damage of Materials: Diagnostics and Prediction” Determination of porous constructions heat transfer coefficient Anatolii Pavlenko a , Andrii Cheilytko b , Serhii Ilin b , Yuriy Belokon c * a Department of Building Physics and Renewable Energy Kielce University of Technology, 7 Al.
