The modeling of turbulent liquid films has been the target of extensive research for the last six decades. However, an in-depth review of the existing works shows that the following questions need to be resolved: Which turbulence model is the most reliable for predictions of heat transfer in turbulent falling liquid films? What are the effects of the interfacial shear, and how do these different turbulence models affect the predictions of heat transfer in the given problems? The main purpose of this paper is to present an improved heat transfer prediction model for turbulent falling liquid films with or without interfacial shear. The present model is partly based on Yih and Liu`s unified approach and Mudawwar and El-Masri`s semiempirical turbulence models. The results from the examination of the effects of turbulence models and the interfacial shear on the heat transfer are also presented.
