Abstract: 

This study delves into the intricate relationship between energy loss coefficients and multiphase flow characteristics in petroleum pipeline systems. Specifically, we focus on the energy loss coefficients K3-1 and K3-2 within a 45° "Yee" pipe divergence, a common configuration in oil and gas transportation. By simulating a wide range of two-phase flow conditions, including liquid-liquid and liquid-solid mixtures with varying fluid properties, water cuts, and particle sizes, we aim to quantify the impact of these parameters on pressure drop and, consequently, energy consumption. 

Our findings underscore the significant influence of fluid viscosity, water cut, dispersed phase particle diameter, and solid particle concentration on the energy loss coefficients. These factors collectively determine the magnitude of pressure losses within the pipeline, directly impacting the overall energy efficiency of the system. By developing a comprehensive understanding of these relationships, we can optimize pipeline designs to minimize pressure drops and reduce pumping requirements. 

The insights gained from this study offer several practical applications for the petroleum industry. Firstly, the ability to accurately predict pressure drop in multiphase pipelines is crucial for ensuring safe and reliable operations. By incorporating the results of this study into engineering design software, engineers can optimize pipeline configurations, reducing the risk of flow assurance issues such as slugging and hydrate formation. Secondly, minimizing pressure losses translates into significant energy savings, reducing operational costs and lowering the overall carbon footprint of petroleum production.
