A two-phase flow model has been developed for analyzing and designing gas/condensate distribution pipeline network system. The model is developed based on looped-system approach with some modifications. In mis model, a phase behavior model is implemented for predicting the fluid properties required for Ihe governing equa-tions for the network system. By utilizing the Linear Theory Method, the Beggs-Brill's two-phase flow model is implemented in this model to predict the hydrDdynamic variables in each leg of the network using lhe iterative technique which is developed in this study. A generalization or the two-phase network model is provided thereby making it possible for the two-phase flow model used In be replaced with any other that may be more applicable for the particular situation. Using the iterative procedure developed, pressure al all nodes, gas flow rate and liquid holdup at each leg can be predicted. The test results demonstrate that the model can serve as a predictive and design tool for solving a two-phase Dow problem in a pipeline network;.
