.... Flow regime were recorded with high speed video cameras. Experimental results were compared with existing models by Barnea (1987) and with a commercial dynamic multiphase flow simulator (OLGA7.3 ® ). Predictions with unified model had acceptable agreement with experimental data. 1. INTRODUCTION...

... ABSTRACT Understanding the dynamics of multiphase flows to enable their accurate and efficient prediction is of central importance in the oil-and-gas industry. Despite the significant advances that have been made in modelling these flows over a number of decades, however, numerous challenges...

...). In internal multiphase flow cases, due to the fluctuation of void fraction, phase distributions, structure velocity, pressure, and momentum flux, turning flow elements (e.g. bends, and tees) can experience periodic forces that may result in vibration of the system. This is called internal multiphase flow...

... Introduction Piping structures are generally subjected to high dynamic loading due to multiphase fluid forces. In particular subsea structures are very vulnerable as large flexibility is required to cope for instance with thermal stresses. The forces due to multiphase flow are characterized...
