This paper deals with several experimental studies in the aim to discuss the relation between heat transfer and skin friction for turbulent wail jet flows, with particular emphasis on the most recent work by Tida (These de Doctorat, Universite de Nantes, 1988). A theoretical study takes stock of the whole of experimental results and draws conclusion on the previsional models related to heat transfer. Two complementary approaches are therefore proposed : an analytical formulation drawn from works by Hammond (Proceedings of the 7th International Heat Transfer Conference, Munich, Vol, 3, pp. 349-355, 1982) and Nizou (Int. J. Heat Mass Transfer 27, 1737-1748, 1984), and calculation included within a more general numerical model of the Phoenics type notably developed by Malin (Ph.D. Thesis, Imperial College of Science and Technology, London, 1986; Appl. Math. Modell. 11, 281-284, 1987).
