Kurzfassung:
A model for gas–liquid annular and stratified flow through a standard Venturi meter is investigated, using the two‐phase hydrokinetics theory. The one‐dimensional momentum equation for gas has been solved in the axial direction of Venturi meters, taking into consideration the factors including the void fraction, the friction between the two phases and the entrainment in the gas core. The distribution of wet gas static pressure between the two pressure tapings of the Venturi meters has been modeled in the pressure range of 0.1–0.6 MPa. Compared with the experimental data, all the relative deviations of the predicted points by the model were within ±15%. As the model is less dependent on the specific empirical apparatus and data, it provides the basis for further establishing a flow measurement model of wet gas which will produce fewer biases in results when it is extrapolated. © 2014 American Institute of Chemical Engineers AIChE J , 61: 699–708, 2015
