EN This chapter presents a review of methods for enhancing the heat transfer during flow of the drag reducing surfactant solutions proposed in the literature. For that type of fluids, the main goal is to increase the heat transfer coefficient to the level obtained during the flow of pure water. Based on the performed analysis of different methods for enhancing the heat transfer, it is clear that none of them can be treated as the universal one. The values of the heat transfer coefficient depend not only on the temperature and concentration of the solution but also on the type of surfactant used. In addition, the experimental results on heat transfer enhancement are presented only in graphical form. This means that the results published in the literature may be applied in practice only in the case when a flow system used is the same as a solution of surfactant in modelling studies and temperature conditions are similar.
