LedaFlow is the product of ten years of innovative development by SINTEF sponsored, guided and supported by TOTAL and ConocoPhillips, now commercialised and developed further by Kongsberg. LedaFlow® is based on models that are closer to the actual physics of multiphase flow and provides a step change in detail, fidelity, quality, accuracy and flexibility over existing multiphase flow simulation technology. LedaFlow has been extensively validated against the best available and most comprehensive experimental data sets to ensure that the models are as representative as possible. LedaFlow is designed with an intuitive user interface to ensure that productivity is improved and with a comprehensive relational database to ensure that all cases are stored and readily available.
