Abstract
A thermal diffusion process proceedings in heterogeneous domain Ω = Ω1
and the following boundary-initial conditions
where C e , λ e , q Ve , e=1, 2 are the thermophysical parameters and capacities of internal heat sources, ∂ t T=∂T/∂t, ∂ n T is a normal derivative at the point X∈Γ, R(X, t) is a thermal resistance between sub-domains considered, Γ10, Γ20 form the outer surface of the system. In the case R(X, t)=0 the heat flux continuity condition resolves itself into the condition additionally determining a continuity of temperature field. The domain considered is shown in Fig. 1.
