WebApr 15, 2024 · Regime maps are presented showing the effect of liquid velocity on transition gas velocity and gas holdup along all three transition boundaries. The liquid velocity advances the onset of discrete bubbling regime, helical flow regime and churn-turbulent regime. Gas holdup increases with an increase in gas and liquid velocities. WebThe flow regime map comprises different zones according to bubble coalesce phenomena. The isolated bubble (IB) regime is characterized by higher bubble generation rate compared to bubble coalescence rate. Either or both bubbly flow and slug flow appear.
WebJun 14, 2024 · A colorimetric technique with the oxygen sensitive dye resazurin was investigated to visualize gas-liquid mass transfer during slug flow, bubble deformation, as well as laminar and turbulent bubble breakup in the wake of a micronozzle. WebJun 1, 2024 · Slug flow was only observed at 0.2 MPa but replaced by block-bubble flow at 1.0 MPa. Flow pattern maps at the pressure of 0.2 MPa and 1.0 MPa were plotted and the difference was analyzed ...
WebFlow regime maps of ( a) LL-Rhombus and ( b) LL-Triangle, with deionized water as liquid phase. Bubble flow can also be less predominant in the LL-Triangle than in the LL-Rhombus since the flat wall of the triangular obstacle impinges on incoming flow and abruptly redirects it toward the curved sides of the mixer [ 17 ].
WebThe application of flow regime models for slug flow for pipe diameters between 1 and 4 inches is widely used in empirical and mechanistic models in the oil and gas industry. … joy thru fresnoWebJul 1, 1998 · According to Spedding et al. [30], flow patterns of two-phase flow in vertical downward tubes were classified into four categories, i.e., bubbly flow (B), slug flow (S), churn flow (C), and annular flow (A) based on the two-phase flow photos obtained with the high speed camera and the differential pressure signals which have different … joy thru incWebDec 14, 2024 · A proposal of the flow regime map of the bubble-induced inverse three-phase fluidization including four flow regimes is shown in Fig. 8.
