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...

TechTip: Momentum Recovery in Tubeside Vacuum Condensers
February 01, 2017
Traditionally, for tubeside vacuum condensers, designers attempt to ensure that the velocity profile through the exchanger decelerates from the inlet nozzle to the outlet nozzle. Momentum recovery occurs with a reducing velocity profile throughout an exchanger. If correlations do not account for momentum recovery in the inlet and outlet header of...
