MODELING AND CALCULATION OF TWO-DIMENSIONALLY ORIENTED THERMAL CONDUCTIVITY OF HETEROGENEOUS COMPOSITIONS

Annotation

A method for modeling a two-component composite material is considered to describe the anisotropy of thermal conductivity of its two-dimensionally oriented structure. The method consists of modeling the structure of the composite under study and subsequent calculation of its thermal conductivity using design relationships that are based on the well-known electrothermal analogy. In the method under consideration, the structure of a real composite is modeled by an elementary cell, which is a cube with edges of unit length. The final system of equations for calculating two-dimensionally oriented thermal conductivity is presented, an example is given, and an estimate of the expected accuracy of thermal conductivity prediction is given.
