摘要：

The hydrodynamics in turbulent film flows will be described at present mostly by using empirical quantities. Subject of the analyses shown in this paper is a turbulence modelling using spin balance. Therefore it was necessary to make a special formulation of the induction terms, where the momentum transfer can be described without additional empirical statements. The velocity and spin profiles are physically useful. A suitable consideration of analogy between hydrodynamics and heat transfer make it possible to calculate the local heat-transfer coefficients. The comparison with experimental data of various authors shows a good correspondence in a wide range of physical properties and liquid load. Similar statements can be given for the modelling of mass transfer in the film.
