... of phase k Mk Momentum transfer of phase k 5© BHR Group 2005 Multiphase Production Technology 12 1 INTRODUCTION One of the big issues in the oil and gas industries is the understanding of the behaviour of multiphase mixtures in pipeline transport. Indeed, it is important to be able to predict the gas...
