LedaFlow Engineering 1D is an advanced transient multiphase flow simulator that models the dynamics of multiple fluid phases within well and pipe networks.
LedaFlow is the product of many years of innovative development by SINTEF; sponsored, guided and supported by TOTAL and ConocoPhillips, commercialized and developed further by KONGSBERG.
LedaFlow is based on models that are closer to the actual physics of multiphase flow. It increases the resolution of modelling, solving mass, energy, and momentum conservation for each of the three phases of multiphase flow (oil, gas and water). This improves the accuracy in simulation of critical transient events and consequently provides a step change in the understanding of fluid behaviour. More physically correct models also provide better scalability.
It solves mass equations for all nine fields (dispersed and continuous) of the three phase flow (oil, gas and water) while the energy and momentum conservation are solved for each zone (continuous phase with the dispersed phases it contains). This improves the accuracy in simulation of critical transient events and consequently provides a step change in the understanding of fluid behavior.
As LedaFlow solves separate energy equations for all three phases, much more accurate information can be determined during stratified flow and during blow down conditions where the temperature of the slower moving liquids at the bottom of a pipe can differ considerably from the gas flowing above. In addition, a buried pipe model provides the user with a heat conduction model from the inner surface of the pipe through to the exterior surface of the soil. This is particularly important for estimating corrosion rates and pipe-wall temperatures, information that is critical for material selection and for hydrate risks prediction.
LedaFlow can be used by multiple disciplines throughout the project lifecycle to address gas/liquid, thermal, solid and integrity management challenges.
