Two-Phase Pipe Flow

The design of two-phase pipe flow systems is often a complex phenomenon. FluidFlow is used by engineers to calculate pressure losses and flow distribution in two-phase pipe flow systems.

FluidFlow uses a modelling approach for the pressure loss calculation which is a hybrid between the rigorous and empirical methods. This means the software uses well known empirical correlations which are applied to a differential pipe length, allowing for a flash calculation, liquid holdup and flow regime to be determined for each segment and acknowledges that the pressure loss per unit length changes as the two-phase mixture flows along the pipeline.

FluidFlow is used by engineers to:

  • Automatically size pipes, ducts, fans, compressors, control valves, safety relief devices, orifice plates and nozzles.
  • Study plant performance & determine fluid physical properties throughout an entire system.
  • Conduct thermal heat transfer analysis for pipes and fittings.
  • Evaluate vendor booster performance and identify energy saving opportunities.
  • Monitor steam quality.

Features:

  • Automatically size pipes, ducts, fans, compressors, control valves, safety relief devices, orifice plates and nozzles.
  • Highly accurate results developed using a “marching” solution algorithm.
  • Comprehensive fluid, component and insulation database, as standard.
  • Quickly and easily add fluids and components to master database.
  • Eight available two-phase correlations.
  • Flow pattern maps automatically generated for each pipe segment.
  • Composite booster curves (Series and Parallel).
  • System design solution using real gas conditions for gas phase.

Our customers use FluidFlow to model:

  • Flashing steam / water systems.
  • LNG processing facilities.
  • Power generation and utilities.
  • Geothermal plant.
  • Cryogenic and ammonia systems.
  • Model rocket propulsion systems.
  • Design petrochemical plant pipework.

London Marine Consultants (LMC) specialises in the design of external turret mooring systems for FPSOs, FSRUs and FSOs. FluidFlow was used during the engineering phase of different projects to ensure that the turret’s complex swivel system and its surrounding pipe network were the most adequate and met all of the client’s requirements (i.e. pipe size, pressure drop, velocity etc).

FluidFlow was the perfect software for this job:

  • We had a powerful tool that allowed us to model a system as complex as a swivel and optimize its surrounding pipe network,
  • The interface is user ­friendly and yet very accurate (large database, various correlations can be used, modelling of multi­phase flow, results can be exported and treated in Excel)
  • And finally the FluidFlow team is very knowledgeable and always prompt to respond whenever needed.
