Flow Dynamics and Breakdown of Falling Liquid Films on the Heated Smooth and Structured Surface
This paper presents the experimental results on heat transfer and hydrodynamics of the falling films of binary Freon mixtures on the tubes with smooth and textured surfaces. The range of Re number alteration at the working section inlet was Re = 10-155. The wave surface of the falling liquid film and the process of dry spot formation were recorded by the high-speed digital video camera. Results of investigation of the wave surface structure, measurements of heat transfer coefficients and dynamics of dry spot formation on the heated surface with corresponding critical heat fluxes are shown in this paper.
