The flow pattern map coordinates presented in Fig. 6,
are established from eight flow-rates pairs (Ql, Qg) and for three liquid
solutions. the plotted frontier corresponds
to the transition between the two flow regimes observed
within the experimental range, which are the ‘‘dispersed’’ regime
that allows a complete incorporation of the gas, and the so called
‘‘slug flow’’
of iso-values; but of course
the validity is limited to the bubble regime area. Some representative
experimental values taken at the frontiers are gathered in
Table 5.
