PLAIN TUBE

This webinar reviews improvements in boiling heat transfer through the use of passive surface enhancements. Commercial tubes enhanced with porous coatings or mechanically with integral structure provide a larger surface area for heat transfer and nucleation site density when compared with plain tubes. Boiling heat transfer enhancement for clean fluids increases...

This webinar will discuss flow boiling data across ideal plain tube bundles collected in the HTRI Multipurpose Boiling Unit and compiled from the literature. Our current method has four heat transfer mechanisms: nucleate boiling, convective boiling, thin liquid film conduction, and natural convection. It is complex with many correlation parameters and...

HTRI continues to improve its single-phase crossflow methods. We have completed a thorough review of heat transfer and pressure drop correlations for single-phase flow outside banks of plain- and low-finned tubes. This webinar highlights some of our findings and summarizes the performance of the improvements we are proposing for our correlations....

Vertical shellside boiling is used for a variety of applications, including vertical thermosiphon reboilers where hot fluid must be on the tubeside steam generators/waste heat boilers, which use very hot or corrosive fluids as the heating medium vertical feed-effluent exchangers, whose vertical orientation prevents phase separation Ideal vertical shellside reboilers have...
