Compositional multiphase hydrodynamic modeling of gas/gas-condensate dispersed flow in gas pipelines

A nonisothermal 1D steady-state compositional two-phase hydrodynamic model describes the formation and flow dynamics of gas condensate in horizontal natural gas pipelines. The two major constituents of the model, hydrodynamics and phase behavior, are coupled through the phase-generation/disappearance-related terms in the continuity and momentum equations. The model is demonstrably capable of predicting the amount, quantity, and distribution of condensate in the pipeline, in addition to the other commonly sought engineering design variables. Parametric studies show that the model is capable of predicting the phenomena associated with gas condensation in pipelines.
