WebIt was found that the Wang flow pattern map was more accurate than the Mohseni flow pattern map. Specifically, the Wang flow pattern map (θ = 45°) identified the stratified and annular flows well for small tube diameters, but its prediction accuracy decreased for large tube diameters. Furthermore, the study revealed that the Weber number was ... WebSep 7, 2010 · Flow pattern map for horizontal co-current flow obtained by Taitel and Dukler (1976). (See Dukler and Taitel, 1986). Taitel et al. (1980) also produced a flow pattern map for vertical flow, but this has met with less widespread use. Following similar approaches, Barnea (1987) has produced a unified model for flow pattern transitions for the ...
