“…Zhai et al [24] Wire-mesh sensor -1 ms -2 mm Y Maximum relative error of average interfacial height: <10% Tiwari et al [25] Electrode matrices conducted an experimental study on the three-dimensional (3D) morphology of long bubbles in horizontal slug flow using a high-speed camera, providing a complete characterization of the nose, body, hydraulic jump, and tail of long bubbles, while also exploring the length-area-volume properties of long bubbles. Roitberg et al [8] discovered that for shallow inclinations, the shape of the long bubble nose primarily depends on mixture velocity, while for steeper inclinations, the effects of the inclination angle become more pronounced.…”

In horizontal intermittent flow, the long bubbles move toward the center of the pipe due to inertia, forming the thin liquid film above the long bubbles. Accurate measurement of the liquid film thickness is crucial for heat and mass transfer. In this paper, laser interferometric technology is innovatively introduced to measure the film thickness of the intermittent flow, and the thin liquid film is detected with a resolution of 100 nm. Considering the curvature of the circular pipe wall, which leads to divergent reflected light, the effect of the pipe wall on the interference pattern is explored by the ray tracing technique. A two-dimensional interpolation phase retrieval algorithm based on light intensity is proposed to reconstruct the thickness of the liquid film, and the average error is less than 1.86%. Benefiting from the exceptionally high resolution, research is conducted on the thin liquid film at the top of the horizontal intermittent flow, revealing its dependence on the sub-regimes and gas-liquid velocities.
