BK1-17 Improvements to HTRI 1D Kettle Circulation Model
October 18, 2022
This report discusses bundle pressure drop and recirculation flow rate measurements. Comparing HTRI data trends to the bundle flow rate measurements from the literature, we developed an improved circulation model for kettle reboilers. The improved model predicts a higher recirculation, especially at a high vapor generation, which also improves the thermal...

BT-41 Pressure drop method for tubeside falling film evaporators
October 19, 2020
HTRI collected data for falling film evaporation in a vertical tube using five test fluids. This report discusses available pressure drop methods and correlations for intube falling film evaporators and investigates correlations for liquid film thickness and void fraction. The report also documents an improved pressure drop method based on the...

Educational: Introduction to Two-phase Flow
December 04, 2018
Boiling, condensation, and multi-phase flows exist in many heat exchanger applications. This webinar describes the basic ideas used in heat transfer and pressure drop calculations of two-phase flow. It discusses theoretical and empirical models, a flow regime-based approach, and an overview of experimental research in the field....
