... and thermodynamic wax models may affect the predictions of wax deposition rate and pigging frequency. The fluid flow models considered include the steady-state multiphase OLGAS® and Beggs-Brill model. The thermodynamic wax models of Coutinho and an ideal mixing approach will be compared. Real field cases...

... to assess prediction uncertainties we are in this work proposing a new method to specify flow model uncertainties. First we have reviewed a comprehensive database of laboratory measurements of primarily pressure drop and holdup. Datasets are grouped according to flow conditions. The most significant flow...

... ABSTRACT Parameters related to the drift-flux (DF) 2-phase flow model are optimized to improve predictive performance. To facilitate this work, an extensive data review was performed resulting in the construction of a generalized, consistent and uniform data bank (suitable for all 2- and 3...
