WebMar 15, 2024 · A two-phase flow in flat minichannels and microchannels with a height range of 50–1 mm and width range of 10–40 mm was experimentally investigated. The flow regimes were determined and regime maps were constructed. The characteristics of two-phase flows have been studied using laser-induced fluorescence and Schlieren … WebThis equation is usually adapted for two-phase flow by assuming that the two-phase flow regime and two-phase properties can be considered homogeneous over a finite volume of the pipe. ...

WebMay 9, 2024 · The transition for two-phase flow agreed well with the flow regime map proposed by Kong and Kim , and a strong dependency of the boundary with the solid concentration was found for three-phase flows. For a specific slurry velocity ( \(j_{fs}\) ) higher flow rates of the gas phase are needed to reach the boundary as the solid …

WebApr 1, 1999 · With the partially wetting combinations, their flow regime maps were similar and had minor differences with the flow regime map of Damianides and Westwater (1988) for 1 mm-diameter channel. With θ =34° (obtained with a Pyrex test section), however, they observed stratified–wavy flow in the U GS ≲0.01 m/s and 10 m/s≲ U LS ≲100 m/s range.
