Two-Phase Pipe Flow

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.
