Some characteristics of gas-liquid flow in narrow rectangular ducts
TLDR
In this paper, the authors measured void fraction, slug bubble velocity, and pressure loss for rectangular ducts with a narrow gap and a large aspect ratio using the neutron radiography technique, and the void fraction was well-correlated by the drift flux model with the existing correlation for the distribution parameter.About:

Some characteristics of air-water two-phase flow in small diameter vertical tubes
Kaichiro Mishima,Takashi Hibiki +1 more
TL;DR: In this article, the authors measured air-water flows in capillary tubes with inner diameters in the range from 1 to 4 mm and found that the boundary between flow regimes was predicted well by Mishima-Ishii's model.

Pressure drop correlations for two-phase flow within horizontal rectangular channels with small heights
Han Ju Lee,Sang Yong Lee +1 more
TL;DR: In this article, the two-phase frictional multiplier was expressed using the Lockhart-Martinelli type correlation but with the modification on parameter C. The correlations with the modified C successfully cover wide ranges of the Martinelli parameter (X=0.303-79.4) and the all-liquid Reynolds number (ReLo=175-17700) based on the hydraulic diameter within the deviation of ±10%.
