MultiFlowMet II will run from 2017 to 2020 and expands on the work of MultiFlowMet I. More partners and test laboratories are taking part in the intercomparison providing Europe with greater confidence in its multiphase flow measurement infrastructure through harmonisation of multiphase flow measurement methods and data.
The preceding EMRP project ENG58 MultiFlowMet developed and piloted an approach for such harmonisation. However, this approach now needs trialling and applying across an enlarged network of laboratories and a wider range of multiphase metering types, which the current project will address.
Technical Aims and Objectives
1. To optimise, and fully prepare for the intercomparison test programme by building a transfer package whilst considering leading-edge methods of flow pattern visualisation and producing a comprehensive set of test matrices and protocols.
2. To carry out intercomparison testing across a network of laboratories with appropriate facilities to significantly extend the test envelope. The intercomparison testing will include appropriate leading-edge methods of flow pattern visualisation and will be done across meters incorporating a range of technologies (e.g. Venturi, cross-correlation, gamma ray absorption, electrical impedance sensing, Coriolis and phase separation technologies).
3. To further develop modelling (e.g. computational fluid dynamics (CFD) technologies for significantly improving the metrological characterisation of multiphase flows, using small and full-scale experimental testing. Improvements will come from new data that will allow flow regime map(s) to be extended and/or new one(s) created. This will include additional research to understand geometrical influences and the influence of gas phase activity.
4. To make statistical cross-comparisons between the measurements undertaken in each intercomparison laboratory with a view to establishing comparability of measurements between test laboratories. The analysis will compare findings, identify anomalies, deduce their method of investigation and state the resolutions achieved.
