In the preceding proposed work scope, experimental and analytical studies of supercritical flow in a natural-convection loop were undertaken. The studies focused on pressure drop and the onset of flow instability in natural circulation. Also, analytical studies were conducted of parallel-channel flow instability. Non-dimensional parameters defining the instability boundary of static as well as dynamic instability were developed and tested using a linear stability program and studying a large number of cases.

在前面提出的工作范围内，进行了自然对流回路中超临界流的实验和分析研究。 研究的重点是自然循环中的压降和流动不稳定性的开始。 此外，还对平行通道流动不稳定性进行了分析研究。 定义静态和动态不稳定性的不稳定边界的无量纲参数的开发和测试使用线性稳定性程序和研究大量的情况。
