S-SS-3-30 Predictions of Single-phase Flow in TEMA F-shell Heat Exchanger: CFD vs. Xist
December 21, 2022This report compares computational fluid dynamics (CFD) and Xist predictions of single-phase performance in a TEMA F-shell heat exchanger with a sealed longitudinal baffle. In the initial comparison, CFD underpredicted both duty (16% less) and pressure drop (over 50% less). We then represented an F shell in Xist using two E-shell...
S-ST-1-17 Using Neural Networks for Predicting Nusselt Number for Intube Laminar Flows
July 25, 2022Neural networks can be used to predict the Nusselt number for intube laminar flow. In addition to describing the architecture of a neural network, this report discusses the application of a neural network to a manufactured data set, open literature data, HTRI data, and CFD simulation results. Our results illustrate the...
PHE-17-TR Liquid-phase and Boiling Testing in a Welded Plate Heat Exchanger
March 07, 2018HTRI 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...
