该论文报告了超临界压力下不同流体之间的比较结果，该结果基于最近提出的相似性原则，以建立流体与流体比较的理论基础。在过去的工作中提出的无因次组的流动稳定性的分析，在超临界压力下的流体加热通道，最近扩展到一般的传热条件下，为了规模也热物理性能组具有相关的传热。通过使用考虑不同流体的CFD代码并得出有关其适用性的结论，对这种新原理的能力进行了研究。
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.
