测量了水平平行板之间厚度为5-100 μm的极窄通道中N 2 -R113绝热气液两相流的流型、压降、空隙率和相速度。实验表明，两相流的摩擦系数小于适用于正常尺寸通道的 Chisholm 相关式，并且随着通道变窄，空隙率也变小。提出了经验相关性
Flow pattern, pressure drop, void fraction, and phase velocity are measured for N 2 -R113 adiabatic gas-liquid two-phase flow in extremely narrow channels with a thickness of 5-100 μm between horizontal parallel plates. It is clarified from the experiments that the friction multiplier of two-phase flow is smaller than Chisholm's correlation applied for normal-sized channels, and that the void fraction becomes smaller as the channel becomes narrower. Empirical correlations are proposed
