Abstract

The paper reports on the results of a comparison between different fluids at supercritical pressures, basing on similarity principles recently proposed to establish a rationale for fluid-to-fluid comparison. The dimensionless groups proposed in past work for the analysis of flow stability in heated channels with fluids at supercritical pressure were recently extended to general heat transfer conditions, in order to scale also thermo-physical property groups having relevance for heat transfer. The capabilities of this new rationale are investigated by the use of a CFD code considering different fluids and drawing conclusions about its suitability.
