S-ST-1-18 Modified Tubeside Heat Transfer Method for Supercritical Carbon Dioxide and Water
July 10, 2023
Further analysis of data summarized in STG-22 leads to a simplified modeling option that improves the prediction of tubeside heat transfer data reported in literature for supercritical water and carbon dioxide. The new approach applies a multiplier to the HTRI single-phase correlation and decreases the heat transfer overprediction near the maximum...

S-SS-3-30 Predictions of Single-phase Flow in TEMA F-shell Heat Exchanger: CFD vs. Xist
December 21, 2022
This 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, 2022
Neural 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...
