As part of the development of the LedaFlow multiphase simulation tool, experiments have been performed to investigate detailed flux- and velocity profiles in two-phase flows with Nitrogen and Naphtha. The experiments have been recorded in an 8 inch diameter pipe with 0.5° inclination at 20 and 90 bar pressure. Results and implications from these measurements are discussed. Next, a detailed model for droplet entrainment is presented. The experimental data is analysed based on the proposed model framework and the model is calibrated using the available measurements. The subsequent results are discussed.
