Project summary

Basing on the recent research, foundation of the new scientific branch is expected, namely, theoretical background of heat conductivity of non-homogeneous materials.

Within the framework of the project, a new mathematical model of heterogeneous material structure shall be created relying on the concept of chaotic spatial distribution of filler particles based on the theory of probability. Development of the theoretical background of heat conductivity of non-homogeneous materials shall be carried out and essentially new, more general (as compared to the existing ones) methods for calculation of heat conductivity of heterogeneous materials shall be developed applicable for both homogeneous and inhomogeneous materials. Experimental determining of thermal properties of heterogeneous composites of various types (porous and building materials, heat insulators, ceramics, cokes, et al.) at different temperatures shell be carried out at the commercial plant IT-l-400.

Basing on comparison of theory and experimental data, quantitative estimations of the calculation precision shall be carrier out. PC software shall be developed for calculation of the heat conductivity.

The work shall be implemented on the basis of ideas and studies carried out by participants within last two to three years.
