SuperCritical Fluids (SCFs) have been used for some time in various industries, but still up till now their wide application is limited due to incomplete knowledge of specifics of thermophysical properties and heat transfer of these fluids. The most widely used SCFs are water and carbon dioxide. Supercritical water is proposed as a coolant in Generation IV nuclear-reactor concept - a SuperCritical Water-cooled Reactor (SCWR) and as a working fluid in supercritical-pressure Rankine steam cycle in other Gen IV concepts. However, water is not compatible with sodium, molten salts and due to that for reactors with these coolants SuperCritical (SC) carbon dioxide is proposed as a working fluid in the power cycle - Brayton gas-turbine cycle. Therefore, knowledge of specifics of thermophysical properties and heat transfer to SC carbon dioxide is very important for development of power cycles for Sodium Fast Reactor (SFR) and Molten Salt Reactor (MSR). Unfortunately,

超临界流体（SCF）已在各个行业使用了一段时间，但是直到现在，由于对热物理性能的细节不完整以及这些流体的热传递，它们的广泛应用受到限制。使用最广泛的SCF是水和二氧化碳。超临界水是在IV代核反应器概念中作为冷却剂的 - 一种超临界水冷却反应堆（SCWR），并且是其他Gen IV概念中超临界压力朗金蒸汽循环中的工作流体。然而，水与钠，熔融盐不兼容，并且由于这些冷却剂超临界（SC）二氧化碳的反应堆在功率周期中提议是一种工作流体 - 布雷顿气动涡轮循环。因此，了解热物理性能的细节以及热转移到SC二氧化碳对于发展快速反应器（SFR）和熔融盐反应器（MSR）的功率周期非常重要。很遗憾，
