“…The void fraction is estimated to 0.581 with the CISE correlation (Eqs. (4.4)e(4.4.6)) which is considered one of the most appropriate for use in the estimation of void fraction in small channels [33] and inclined narrow annular channels [34]. Recent investigation carried out by Rattner et al [35,36] in 2015, demonstrated experimentally that intermediate scale Taylor The mechanistic models that directly account for Taylor bubble length fraction and liquid film thickness will be exploited in our future investigations.…”

“…In the minichannel one can observe various flows types including isolated, confined, and elongated bubbles, slugs and semi-annular flows, as well as churn and annular flows [1][2][3]. The liquid flows which accompany the bubble flows can be laminar and turbulent depending on the liquid and gas flow rates [4].…”

Abstract. The churn-to-slug flow bifurcations of two-phase (air-water) flow patterns in a 2 mm diameter minichannel were investigated. With increasing a water flow rate, we observed the transition of slugs to bubbles of different sizes. The process was recorded by a digital camera. The sequences of light transmission time series were recorded by a laser-phototransistor sensor, and then analyzed using the recurrence plots and recurrence quantification analysis (RQA). Due to volume dependence of bubbles velocities, we observed the formation of periodic modulations in the laser signal.

“…The trend of developing applications for ocean environments has attracted growing interests on two-phase flow under inclined condition. Therefore, the flow pattern, void fraction, and pressure drop of two-phase flow in inclined tubes have been studied extensively [21][22][23][24][25]. However, only very few literatures have focused on the local interfacial parameter distribution under inclined condition.…”

An experimental investigation of phase distribution for subcooled flow boiling in an inclined circular tube (i.d. 24 mm) was conducted in this paper. The local interfacial parameters were measured by a double-sensor optical fiber probe, and the measurements were performed on three different directions in the inclined tube cross section. The experiment shows that the phase distribution under the inclined condition is different from the phase distribution under the vertical condition. The profiles skewed highly for 90°and 45°direction in the tube cross section, whereas the profile was also symmetrical at 0°direction. These results can be explained by the fact that buoyancy caused the bubbles to move toward the top of the tube cross section under inclined condition. In addition, the typical distributions were also influenced by the inclination angles.
