Research Update: Crossflow Mixed Convection Heat Transfer for Horizontal Tube Banks
January 15, 2017
This webinar reviews measurement of mixed convection heat transfer using liquids in crossflow over ideal horizontal plain and low-finned tube banks. We identify when natural convection may enhance or penalize crossflow heat transfer and recommend new calculations to improve HTRI software predictions....

S-SS-3-29: CFD Simulations of Diabatic Shellside Viscous Flows
January 16, 2017
For shellside diabatic flows of highly viscous fluids, Xist can predict inconsistent pressure drops and heat transfer coefficients. HTRI examined the transition between forced and natural convection in single-segmental and double-segmental exchangers with Alta-Vis oil and an asphalt blend as test fluids. Comparisons were made between experimental data, open literature, computational...

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...
