Porous structures and their effect on thermophysical properties of thermal protection elements

Pavlenko A. M., Cheilytko A., Ilin S.

Journal of New Technologies in Environmental Science

2018

Vol. 2, nr 3

125--133

The improvement of the thermal insulating material thermophysical characteristics of the thermal protection elements by studying the porous structure is a promising direction of research. The article describes the effects of the porosity and coupling of the porous structure on the thermophysical characteristics of thermal insulating materials. The article uses standard systematized techniques and instruments of scientific research applied in thermophysics. The research methodology of highly-porous material thermophysical properties is based on performance of empirical laboratory investigations of the samples obtained.

Mathematical solution to the problem of obtaining massive amorphous structures
