.... 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...

The slug formation in the M-shaped jumper is predicted using a multiphase CFD model which is first validated on a simplified geometry comprising of a straight section and a 90 degree bend. For this simplified geometry, CFD prediction of slug is compared to experimental data obtained by the state...
