THERMAL CONDUCTIVITY OF A THREE-DIMENSIONAL BODY WITH A ROUGH INCLUSIONI. T. Denisyuk UDC 536.2 Thermal conductivity of a three-dimensional body with a rough inclusion is studied. The problem is reduced to the problem of conjugation of harmonic functions and its exact solution is constructed. Distributions of temperature and heat-flux density near distinctions of the interface between media are found. Results are illustrated by a numerical example.
