Heat transfer in packed beds of crushed rock
… was only 12-13 %, occurring between the Reynolds numbers of 1600 and 3200. The experimental uncertainty in the heat transfer coefficient was ± 5.14 %. Based on the experimental data, a new Nusselt number correlation was developed. This correlation compared well with previously well-known Nusselt …

An Effective Methodology for Thermal-Hydraulics Analysis of a VHTR Core and Fuel Elements
… heat transfer coefficient is calculated using a Nusselt number correlation, developed and validated in this work. In addition to omitting the numerical meshing in the coolant channels, the simplified analysis methodology effectively decreases the total computation time by a factor of ~ 33 - 40 …

Specifics of forced-convection heat transfer in a vertical 7-element bundle cooled with upward flow of SuperCritical Water
… configurations is required. Many empirical Nusselt number (Nu) correlations derived from bare tubes are available, with only one derived from a bundle. No assessments of Nu correlations are available for 7-rod bundle datasets, representing the centre of 37-element bundles currently used in …

Improved closure relations for the two fluid-model in flashing flows
… concentration are available such as the static correlations and the Interfacial Area Transport Equation (IATE). In this work, the closure models of the two-fluid model, particularly those of the mass conservation equation, are studied and validated under flashing conditions with additional …
