ABSTRACT
In essence, the conjugate heat transfer problem considers the thermal interaction between a body and a fluid flowing over or inside it. As a result of such interaction, a particular temperature distribution establishes on the body-fluid interface. This temperature field determines the heat flux distribution on the interface and virtually the intensity of heat transfer. Hence, the properties of heat transfer of any conjugate problem are actually the same as those of some nonisothermal surface with the same temperature field, no matter how this field is established, as a result of conjugate heat transfer or given a priori. Thus, in general, a theory of conjugate heat transfer is in fact a theory of an arbitrary nonisothermal surface, because the temperature distribution on the interface in a conjugate problem is unknown a priori.
