LEDA: The Next Multiphase Flow Performance Simulator

LEDA is a new transient multiphase flow simulator with improved models and numerics, with both 1D and multidimensional capability. The approach in LEDA is to improve the accuracy and scale-up capability of the model by including more fundamental physics, rather than relying on more empirical models. LEDA has shown excellent agreement with the SINTEF multiphase laboratory database, and considerably improved scaling performance against TOTAL and COP field data over other available models. We will present an overview of the LEDA 1D models, including some theoretical and numerical background, as well as some selected experimental benchmarking and field cases. Focus will be primarily on the horizontal configuration (pipelines). In addition, we will present some results illustrating the use of the Quasi-3D model, compared to experimental data.
