“…2.1 Two-phase flow mapping Garimella [1], Garimella et al [2], Coleman and Garimella [3], El Hajal et al [4], Thome et al [5], Didi et al [6], Zurcher et al [7][8], Mandhane et al [9], and Baker [10] have all described the importance of using flow pattern information in the determination of accurate two-phase flow models. Consequently, much attention has been directed towards developing two-phase flow regime maps.…”
