FIELD: power engineering.
SUBSTANCE: core sample is prepared, and an X-ray microcomputer tomograph for scanning of the specified core sample and production of the image for each scanning, the specified core sample is scanned, a 3D scanned image is sent from the tomograph to the computer for processing, and the computer is designed for analysis of images, they set thickness of the layer inside the produced 3D scanned image for analysis, they determine the layer with the maximum heat resistance inside the produced 3D scanned image and determine the efficient heat conductivity of the core sample.
EFFECT: provision of the possibility for quick assessment of efficient heat conductivity that does not require numerical solution of a heat conductivity equation.
