Abstract: This invention relates to a computer-implemented method for predicting fluid behaviour in pipeline-based multiphase flows, wherein the method comprises applying a one-dimensional computational fluid dynamic applying a finite volume method in the solver and which estimates the mass flux out of the finite control volumes by i) applying a polynomial to spatially reconstruct the mass present in each finite control volume, ii) reconstructing the flow velocity as a function of the x-component of the flow velocity vector to determine a domain of dependence for each finite control volume representing the distance the fluid has travelled during a time step, and iii) sum the spatially reconstructed mass being present in the domain of dependence for each finite control volume and assume the summarised mass passes out of the respective finite control volume over the applied time step.
