METHOD FOR ESTIMATING HEAT-PROTECTIVE PROPERTIES OF EXTERNAL PROTECTIVE STRUCTURES OF BUILDINGS AND STRUCTURES UNDER CONDITIONS OF NON-STATIONARY HEAT TRANSMISSION ON BASIS OF RESULTS OF TESTS PERFORMED UNDER NATURAL CONDITIONS

摘要

FIELD: technology for determining thermo-physical properties of products.;SUBSTANCE: in the method for considering direction of thermal flow through external boundary structure and instability of heat transmission in it during required standardized period until the moment the testing beings, unstable heat transmission process modeling is conducted using heat transmission equation through multilayer protective structures under initial and boundary conditions, adapted to direction of heat stream, with usage of data of independent monitoring of external environmental parameters.;EFFECT: possible estimation of heat-protective properties of external protective structures of ground-based, subterranean and underwater buildings and structures for various directions of heat stream through them under conditions of unstable heat transmission with various thermo-physical characteristics of environments, divided by protective structures, possible reduction of time spent performing such an estimation.;1 dwg
