The evaluation of the existing wave frequency correlations was discussed in this paper. Four correlations were tested using the experimental data of the air-water horizontal annular flow in 16 mm and 26 mm inner diameter pipes. Different liquid viscosity and surface tension were used in the experiment. To obtain annular flow pattern, the superficial gas and liquid velocity were set at 12 to 40 m/s and 0.05 to 0.2 m/s, respectively. The wave frequency increases with the increasing of gas and liquid superficial velocity. However, the effect of superficial liquid velocity is less significant than that of superficial gas velocity. The examination of the existing correlations for the wave frequency shows that the accuracy of the correlation is generally only valid for certain cases of experiment and producing large error for the other cases.
