Abstract: Simplifying assumptions and empirical closure relations are often required in existing two-phase flow modeling based on first-principle equations, hence limiting its prediction accuracy and in some instances compromising ...

Abstract: Real-time monitoring of pressure and flow in multiphase flow applications is a critical problem given its economic and safety impacts. Using physics-based models has long been computationally expensive due to the ...

Abstract: Presented are reducedorder models of onedimensional transient twophase gas–liquid flow in pipelines. The proposed model is comprised of a steadystate multiphase flow mechanistic model in series with a transient singlephase ...
