Local test results for two enhanced condensing tubes (next-generation versions of the Wieland Gewa and Wolverine Turbo enhanced condensing tubes) are obtained for refrigerants R-134a and R-236fa on the center row of a three row-wide tube bundle. The "bundl ...
The complexities of two-phase flow and falling-film evaporation on a tube bundle present important challenges in the design of heat exchangers and the understanding of the physical phenomena taking place. The development of structured surfaces to enhance n ...
New predictive methods for falling film condensation on vertical arrays of horizontal tubes using different refrigerants are proposed, based on visual observations revealing that condensate is slung off the array of tubes sideways and significantly affects ...
Many parameters influence the falling-film evaporation process and, despite numerous studies, the basic mechanisms remain only partially clear, making the prediction of heat transfer still mainly an empirical process. The most important thermal design para ...
The complexities of two-phase flow and evaporation on a tube bundle present important problems in the design of heat exchangers and the understanding of the physical phenomena taking place. The development of structured surfaces to enhance boiling heat tra ...
