Research Update: Single-Phase Crossflow Methods
January 15, 2017
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....

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....

PHE-17-TR Liquid-phase and Boiling Testing in a Welded Plate Heat Exchanger
March 07, 2018
HTRI conducted liquid-phase and phase-change experiments in a welded plate heat exchanger (WPHE) provided by Hisaka Works, Ltd. With the test plate pack installed vertically, cold fluid flowed horizontally, and steam condensed downward. We conducted single-phase and boiling tests using p-xylene as the test fluid, as well as boiling tests using...

S-ST-1-14 CFD Study of Single-Phase Laminar Mixed Convection in Inclined Tubes
January 16, 2017
To gain insight into the thermal-hydraulic phenomena associated with mixed convection in internal flows, we used computational fluid dynamics (CFD) to conduct a parametric study of single-phase laminar liquid flows in inclined tubes with isothermal, uniform wall temperatures (UWT). Both heating and cooling processes were simulated to isolate the effects of...

STG-13 Computational Fluid Dynamics Study of Impingement Plates
January 16, 2017
The results of a computational fluid dynamics (CFD) study of impingement devices for inlet nozzles on shell-and-tube heat exchangers reveal the deleterious effects of increased velocity and pressure drop for a number of configurations. Simulations of entry flows with round and square solid plates as well as with rod grids were...
