An investigation has been made into the accuracy of two-phase flow trunk line predictions by a one-dimensional steady flow model for stratified wavy flow in horizontal and inclined pipes. The theoretical model uses a new calculation method for the interfacial friction factor, which becomes a function of the gas velocity via its dependence on waves on the gas/liquid interface. Effects of pipe undulation and interfacial shear on liquid hold-up predictions are identified. Field measurements in long trunk lines with pipe sizes from 20 to 36 inches, in which gas and condensate are transported with a pressure range of 5-11 MPa and liquid/gas ratios up to 390 m3/million Nm3 are very well predicted by the model. Of the causes of a systematic overprediction of liquid hold-ups by some 13 % it is, in particular liquid entrainment that deserves a further modelling effort.
