Analysis of the available data reveals that the parameters of boiling heat transfer depend significantly on the thermophysical properties of the heat-transfer wall and its geometric characteristics (roughness and thickness of the wall). However, it is still difficult to correctly estimate in full the effect of roughness and thickness of the heat-transfer wall. It is possibly because of this that no universal criterial relations exist at present which would enable one to describe the vast array of experimental data on boiling heat transfer. A particular problem is treated in this paper and generalization is given of experimental data on boiling heat transfer of Freons and nitrogen to thick-walled pipes of different thermophysical characteristics and roughness.

“…Rogers (1981) also proposed a laminar analysis which is similar to that of Solan and Zfati (1974). Here a correction factor for interfacial waviness, which had been originally suggested by Kutateladze (1979), was added to improve the heat transfer predictions.…”

Heat transfer analysis of falling film evaporation on a bank of horizontal tubes is investigated in this study. Liquid falling from one tube to the next lower one is considered as a thin liquid jet impinging on the top of the tube with a uniform free falling velocity. The hydrodynamic and thermal solutions are obtained by a finite difference method. In these solutions the heat transfer coefficients are modified to account for waviness.Liquid film thickness and local and average heat transfer coefficients are obtained for the constant heat flux and isothermal boundary conditions. Convective heat transfer effects are shown to be dominant as Peclet number increases. Heat transfer coefficients for the tubes in a tube bank decrease from the first tube onwards until the fully developed region is reached. The present predictions agree favorably with the reported heat transfer data.

“…A range of turbulence models has been considered by those developing falling-film models. Assuming the effects of waviness at the liquid-vapor interface are similar to those for vertical falling films, Kocamustafaogullari and Chen [40] and Rogers [79] applied corrections for such effects to the empirical correlations that were proposed by Zazuli [40] and Kutateladze and Gogonin [81], respectively. It is interesting to note that Marangoni effect is not typically included, but some cases it might be important (such as for a subcooled film [79]).…”
