摘　　要：采用两个相同的加热通道构成试验段,进行并联双通道密度波不稳定性实验研究。主要研究系统压力、质量流速和入口过冷度对流动不稳定性的影响,并给出过冷度-相变数边界。Density wave oscillation phenomenon in parallel channels have been studied though the apparatus consisted of two uniformly heated boiling channel.Various situation of system pressure,mass velocity,inlet subcooing contribution to flow instability was distinguished.Moreover,dimensionless subcooling number ans phase change number boundary data was present.

关 键 词：并联双通道 密度波不稳定性 过冷度-相变数边界
