Heat transfer simulation for industrial applications. Needs, limitations, expectations

The goal of this paper is to present a few problems and difficulties to which heat transfer engineers are confronted. Then, possible ways used to tackle these problems are exposed. The paper shows that in many occasions the approaches used are not completely satisfactory and that some aspects should be improved. It is also the opportunity to underline that even if turbulent heat transfer modelling is very important, from the industrial point of view, it represents often only one part of the problems which need to be addressed to perform a complete numerical simulation.
