Assessment of mechanistic multiphase methods against independent experiments at large pipe diameter
- Creare, Inc., Hanover, NH (USA)
Previously, the mechanistic multiphase methods for pipelines which have been documented in state of the art reports have been compared extensively with laboratory data from Creare/PRC experiments in pipes at 3.5 and 7 inches diameter. The multiphase methods have also been assessed against field data from 17 pipelines. In order to provide the broadest possible assessment of the methods, this report compares the multiphase methods against independent laboratory data at large pipe diameter from the IFP (Boussens), SINTEF (Trondheim), and Harwell facilities at 6, 8, and 12 inch diameters, respectively. The SINTEF and IFP facilities operate at elevated pressure (high gas density) while the Harwell facility operates at low pressures, near one atmosphere. Selected data from each facility have been published in the open literature. These data are primarily for horizontal pipes, although the IFP data include upward and downward inclinations. The mechanistic multiphase methods are in substantial agreement with most of the data from these facilities (especially at high gas density), including the flow regime maps from each facility, pressure drop and holdup data for the stratified flow regime in the SINTEF facility, and flow characteristics in the slug flow regime for the IFP facility. The agreement with the pressure drop in the Harwell facility is not as good as expected, being a factor of two low. 15 figs.
