Conjugate convective heat transfer
The contemporary conjugate heat transfer model was developed after computers came into wide use in order to substitute the empirical relation of proportionality of heat flux to temperature difference with heat transfer coefficient which was the only tool in theoretical heat convection since the times of Newton. This model, based on a strictly mathematically-stated problem, describes the heat transfer between body and flowing over or inside it as a result of interaction of two objects. The physical processes and solutions of governing equations are considered separately for each object in two subdomains. Following conjugation of such obtained results gives the distributions of temperature and heat flux along the body/flow interface, and there is no need in the heat transfer coefficient. Moreover, it may be calculated using these data.
==History==
The term ''conjugate problem'' was coined by a group of scientists led by the academician A. V. Luikov in the former Soviet Union () who, among others in the 1960s, began to investigate heat transfer as a coupled problem. At that time, many other researchers (for example, ()) started to solve simple problems using different approaches and joining the solutions for body and fluid on their interface. A review of early conjugate solutions may be found in the book ().
