Flow regime map two-phase
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 … 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.

For a specific slurry velocity ( \(j_{fs}\) ) higher flow rates of the gas phase are needed to reach the boundary as the solid …
WebJun 15, 2024 · A comprehensive flow regime map was developed based on approximately 250 experimental points covering a wide range of changes of flow parameters for gas−liquid two–phase systems in channels packed with open–cell metal foams where there is no change in the physical state of the mixture components (no evaporation process). WebTL;DR: In this paper, the flow patterns which occur in upward gas-liquid two-phase flow in vertical tubes are described and the use of flow pattern maps is discussed, and the …
WebThe empirical Baker map [16] was a widely used tool based on experimental data of gas-liquid two-phase under adiabatic conditions. However, the ability of the map to predict in-tube condensation flow patterns was debated. Some studies, such as those by Soliman and Azer et al. [17] and Palen [10], found the Baker map
