Bubble flow regime
WebSep 7, 2010 · Flow regimes in horizontal flow are illustrated in Figure 2.Here, as gravity acts normally to flow direction, separation of the flow occurs. The respective flow regimes are Stratified Flow, where the gravitational separation is complete; stratified-wavy flow; Bubble Flow, where the bubbles are dispersed in the liquid continuum (though there is … WebAug 6, 2024 · The flow of dispersed gas bubbles in a viscous liquid can create a bubbly, slug bubble, or elongated bubble flow regime. A slug bubble flow, characterized by bubble sizes equal to the hydraulic diameter of the channel, is a transition regime with a complex local flow field that has received little attention in the past.
