Assessment of Heat Transfer Correlations Against Surrogate Fluid Heat Transfer Data

Abstract

AECL R&D work covers experiments, analysis, subchannel code development and applications, and neutronic and thermalhydraulic coupling analysis to improve the understanding of heat transfer, stability, and critical flow. The latest advances in thermalhydraulics and safety R&D at AECL have been summarized. A compilation of experimental data on heat transfer with supercritical non-aqueous flows over bundle subassemblies and in tubes is presented. Several tube-data-based supercritical heat- transfer correlations were assessed against the bundle data. None of these correlations predict closely the experimental data.
