(32a) Horizons in Multiphase Flow

This presentation reviews the current situation on understanding and predictilon of systems involving multiphase flow. Such systems are typified by hydrocarbon recovery systems where the  flows are commonly gas-liquid, liquid-liquid and gas-liquid-liquid flows. The focus will be on the prediction of  flow regime or flow pattern as a first step. Once the flow pattern is esatblished, then phenomenological models  can be used for the specific regime. The presentation will  cover the principal regimes in both vertical and horizontal flws.
