Orkiszewski's contribution was an original correlation to model slug flow. The
flow map of Orkiszewski (1967) is partitioned by the boundaries of
LB = 1.071 - 0.2218 VM 2
D ; LB ≥ 0.13 (3.80)
LS = 50 + 36 NLV
34
(3.81)
LM = 75 + 84 N LV 0.75 (3.82)
where the dimensionless numbers N LV and N GV , as proposed by Ros (1961), are
NLV = VSL
NGV = VSG

The flow regimes are identified by the following rules:
Bubble

VSG < LB
VM
> LB and N GV < L S
Transition L S < N GV < L M
Annular-Mist L M < N GV
The flow-pattern map suggested by Orkiszewski (1967) is shown in Figure 3.3.
