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）已经在各种工业中使用了一段时间，但是由于对这些流体的热物理性质和传热的细节的不完全了解，到目前为止它们的广泛应用仍然受到限制。最广泛使用的SCF是水和二氧化碳。超临界水被提议作为第四代核反应堆概念中的冷却剂-超临界水冷反应堆（SCWR），并在其他第四代概念中作为超临界压力朗肯蒸汽循环中的工作流体。然而，水与钠、熔盐不相容，并且由于对于具有这些冷却剂的反应堆，超临界（SC）二氧化碳被提议作为动力循环-布雷顿燃气轮机循环中的工作流体。因此，了解SC CO2的热物理性质和传热特性对钠快堆（SFR）和熔盐堆（MSR）动力循环的发展非常重要。不幸的是，
