Testing and Qualification of a New Multiphase Flow Simulator

Abstract: This paper presents test cases, methodologies, and test results from the extensive testing and qualification program that have been conducted with LedaFlow ® . This new transient multiphase flowline simulator has been built with focus on multiphase flow challenges in the oil and gas industry, and the resulting software includes both transient 1D and quasi 3D multiphase models. Development has been based both on existing and new large-scale experimental data from the SINTEF multiphase laboratory, taken over a n… Show more

“…However, even with the present significant advances in computing power, there is still a need to sacrifice accuracy for efficiency in many practical applications. For instance, simulators for petroleum processing facilities often involve the solution of highly complicated multiphase flow models through several kilometer long pipelines [2]. These simulators are typically based on implicit methods, but we may note that explicit methods in the form (3) are trivially parallelizable whereas implicit methods are not [25].…”

“…High fidelity models used for flow assurance and production design include the OLGA (Bendiksen et al, 1991) and LedaFlow (Danielson et al, 2011) commercial simulators. These are both 3-phase flow 1D models, imposing instantaneous pressure equilibrium in all phases.…”

“…Both the OLGA (Bendiksen et al, 1991) and LedaFlow (Danielson et al, 2011) numerical schemes are pressure-based and implicit. The FlowManager TM scheme due to Evje and Flåtten (2006); Holmås and Løvli (2011) is essentially a density-based implicit method, incorporating some ideas from the classical pressure-based schemes.…”

“…A similar concept is applied in LedaFlow, except for LedaFlow using two energy equations and mass balances for all of the possible dispersed fields (in total, nine mass balances). 8 The flow regimes can change along the pipe and in time during dynamic flow simulations. A two-fluid model is typically suitable for separated flows, where the slip can vary very much.…”
