Unformatted text preview: ENU 4134 Bubbly Flow D. Schubring October 4, 2009 Empirical Analysis of Two-Phase Fluid Mechanics Schedule I Flow Regime Maps 1 I Annular Flow 1.5 I Bubbly Flow 0.75 I Other flow regimes (intermittent and horizontal) 0.75 I Counter-current two-phase flow 0.5 I Pressure drop models 2.5 Bubbly Flow Topics I Applicability of previously discussed models. I Other phenomena. I Interfacial area concentration and transport. This discussion will be qualitative. (The sort of thing that might show up in a short essay question.) Applicability of Analytical Models Many of the models discussed in the first two-phase flow block are especially useful for the bubbly flow regime (and into slug flow). The concept of two-phase averaged parameters, such as { } and S , are most relevant in these regimes, as is 2 lo . At high mass flux and pressure, bubbly flow is well-modeled with the HEM....
