CS-24 Shellside Mixture Condensation on Low-finned Tubes in Vacuum Conditions
January 24, 2024
This report describes an assessment of the accuracy of HTRI predictions of mixture condensation on low-finned tubes under vacuum conditions. Tests were conducted on a 19.05-mm OD low-finned tube bundle in the Low Pressure Condensation Unit (LPCU) over a range of vacuum pressures (5.75– 93.7 kPa) and inlet vapor Reynolds numbers...

AC-19 Mixed Convection Heat Transfer Outside High-finned Tube Bundles in Low Airflow
June 23, 2022
Modeling natural-draft air coolers requires accurate prediction of airside heat transfer coefficients at low airflow rates. HTRI has collected additional data from the Air-cooled Unit (ACU) to develop a correlation for mixed convection that predicts low airflow heat transfer. The improved correlation, based on Rayleigh and Reynolds numbers, results in an...

TT-15 Single-phase vapor and condensing heat transfer across inline low-finned tube bundles in cross flow
January 26, 2017
Component: Xace, Xist Applicable to: Version 7.3 and previous Date posted: 22 May 2012 Last updated: 7 September 2017 Externally finned tube bundles can be specified for applications where the outside heat transfer coefficient is less than the inside coefficient. Using inline low-finned tubes in 90-degree layouts allows for cleaning by mechanical means....
