... ABSTRACT An experimental study of vertical two-phase flow was conducted at the SINTEF Multiphase Laboratory using a 51 meter long 4" pipe at system pressures of 45 and 70 bara. This campaign was conducted as part of a project aimed at improving the physical models in LedaFlow for near-vertical...

... and the flowlines connected to it, a process simulator (K-Spice®) is linked to a multiphase pipe flow simulation tool (LedaFlow®). This integrated solution is subsequently linked to Matlab/Simulink for the development of control strategies. Traditionally process simulation modelling of rotating machinery has been...

... performed on the slug capturing modelling approach developed in the LedaFlow project. Slug capturing is based on multi-field stratified flow transport equations, which are formulated and solved. With this technique waves and slugs are resolved on the computational grid using high-order numerical methods...

... ABSTRACT Two commercial multiphase pipe flow simulators, OLGA®5.3 and LedaFlow®, have been tested on laboratory and field data. Regarding the laboratory data, the results are comparable, however, two weak points have been identified: an overprediction of the liquid hold-up in stratified flow...

... ABSTRACT LedaFlow® is a transient multiphase flow simulator under development with both 1D and multidimensional capabilities. The LedaFlow 1D model is a mechanistic, multifluid model consisting of mass, momentum, and energy conservation equations for each field (continuous, bubble and droplet...
