HEAT TRANSFER OF A TURBULENT VERTICALLY FALLING FILM
Résumé
Theoretical and experimental results of the local-heat transfer of a turbulent vertically falling fluid film are presented. The theoretical heat transfer investigations
are based on the semi-empirical theory of turbulence. A satisfactory correlation has been found of experiments and theory in the whole range of Re examined (1800 < Re < 45000). As suggested, the main source of the discrepancy in the heat transfer results of different authors must be the fact of the data applying for the transition region which is noted for a large number of difficult-to-account factors.
