Q7-3 Shellside Condensation in Crossflow

Z. H. Yang

As an initial phase of our new shellside condensation project, HTRI has collected experimental data for shellside condensation in crossflow from one plain tube bundle and one finned tube bundle (748 fins/m (19 fins/in.)) on the Multipurpose Condensation Unit (MCU). We have used these data to evaluate methods for the fully incremental calculation process in Xist™. This article compares heat transfer performance using plain and finned tubes, demonstrates the advantages of finned tubes, and identifies needed improvements to the present finned tube method.
