Abstract: This invention relates to a method for one dimensional simulation of multiphase fluid flow in pipelines enabling determination of pressure drop, fluid volume fractions, and heat and mass transfer coefficients in multiphase pipeline flows, wherein the method comprises providing real world values of the superficial velocities of each of the continuous fluid phases, the pipe diameter, and the inclination angle of the pipeline relative to the horizontal plane, providing initial values describing the flow geometry of the multiphase flow, where the initial values at least comprises the axial pressure gradient and the positions of the large scale interfaces separating the continuous fluid phases, employing a one-dimensional numerical model based on Eulerian formulated transport equations of the multiphase flow in the pipeline, solving the numerical model with the set of input values from step a) and b) to determine the flow parameters of the multiphase flow, and displaying one or more of the determined flow parameters.
