3rd Conference on Flow Problems in Oil & Gas Industry

The 3rd DRG Conference in the Netherlands on Flow Problems in Oil & Gas Industry last September 23rd was a success.


During the morning training sessions two groups gained basic insight in the use of HELYX® CFD and our in-house software package BOSfluids®.


During the afternoon five presentation were given covering a broad spectrum of fluid flow problems related to multiphase flow assurance, pressure surges in pipelines and flow induced vibrations, etc.
