The stability boundary for supercritical flow in natural convection loops: Part I: H2O studies

Non-dimensional parameters governing supercritical flow instability boundary, derived in an earlier study, are now examined through a numerical experiment comprising 94 simulated cases. Part I of this study reports on the stability of supercritical light water in a natural-convection loop and confirms the validity of these non-dimensional parameters for stability predictions. Part II reports on supercritical CO2 and H2.
