2 Application of Universal Functions

In this section, we investigate the effect of different factors on conjugate heat transfer intensity considering the conjugate problem as a case of heat transfer from a surface with variable (nonisothermal) temperature or heat flux. Such an approach is founded on the conception (see Introduction) that a variable temperature (or temperature head) of a body/fluid interface is one of the basic characteristics of any conjugate problem. The results are obtained analyzing universal functions and are supplemented with relevant examples.
